Speaker: Adrian Lozano-Duran, Stanford
Talk Title: Prediction of real-world external aerodynamics using numerical simulations
Abstract: The use of computational fluid dynamics for external aerodynamic applications has been a key tool for aircraft design in the modern aerospace industry. In the last decades, large-eddy simulation with near-wall modeling (wall-modeled LES) has gained momentum as a cost-effective approach for both scientific research and industrial applications. In this talk, we discuss current challenges of wall-modeled LES to become a design tool for the aerospace industry. Our focus is on the working principles and performance of wall-modeled LES for external aerodynamic applications, with emphasis on realistic commercial aircrafts. We examine the computational cost to predict mean flow features and forces for a given degree of accuracy using theory and numerical simulations of the NASA Juncture Flow and the JAXA Standard Model. The vision presented here is motivated by discussions in previous AIAA workshops and the experience acquired at the Center for Turbulence Research during the last years.
Biography: Dr. Adrian Lozano-Duran is a Postdoctoral Research Fellow at the Center for Turbulence Research at Stanford University hosted by Prof. Moin. He received his PhD in Aerospace Engineering from the Technical University of Madrid in 2015 at the Fluid Mechanics Lab. advised by Prof. Jiménez. The overarching theme of his research is physics and modeling of wall-bounded turbulence via theory and computational fluid mechanics. His work covers a wide range of topics, such as turbulence theory and modeling by machine learning, large-eddy simulation for external aerodynamics, geophysical and multiphase flows, among others.

Speaker: Dr. Behrokh Khoshnevis, USC
Talk Title: Robotic Construction by Contour Crafting -“ Future Impacts on Earth and Beyond
Abstract: The nature of construction has remained intensely manual throughout recorded history. Unlike in
manufacturing, the growth of automation in construction has been slow. A promising new automation approach
is construction scale 3D printing, which has been pioneered by the speaker with the invention of Contour
Crafting, a hybrid technology combining concrete 3D printing and a variety of robotics fabrication and
assembly tasks with the aim of automating the entire construction activity. The technology also has astounding
environmental and energy impact potentials. The entry level implication is especially profound for emergency
shelter construction and low-income housing. Exploring possible applications of CC in building on other
planets has also been pursued by the speaker through several projects supported by NASA. This new mode of
construction will be one of the very few feasible approaches for building using insitu material on planets such
as the Moon and Mars, which are being targeted for human colonization before the end of the century.
Biography: Behrokh Berok Khoshnevis has numerous inventions and over 100 US
and international patents as well as nearly 200 refereed technical publications. He is a
member of the National Academy of Engineering, a Fellow of the National Academy of
Inventors inductee, a Fellow of the Society of Manufacturing Engineers, a Fellow of the
Institute of Industrial and Systems Engineering, a Fellow of the Society for Computer
Simulation and a NASA Innovative Advanced Concept Fellow. Because of his Contour
Crafting invention he received the 2014 Grand Prize among 1000 plus globally competing
technologies in the Create the Future design contest which was organized by NASA.
Contour Crafting was selected earlier as one of the top 25 out of more than 4000
candidate inventions by the History Channel Modern Marvels program and the National
Inventors Hall of Fame. The technology has been exhibited in numerous science and technology and art
museums around the world.

Speaker: Daniel Goldman, Georgia Tech
Talk Title: TBD
Abstract: Robots will soon move from the factory floor and into our lives (e.g. autonomous cars, package delivery drones, and search-and-rescue devices). However, compared to living systems, robot capabilities in complex environments are limited. I believe the mindset and tools of physics can help facilitate the creation of robust self-propelled autonomous systems. This robophysics approach -“ the systematic search for novel dynamics and principles in robotic systems -- can aid the computer science and engineering approaches which have proven successful in less complex environments. The rapidly decreasing cost of constructing sophisticated robot models with easy access to significant computational power bodes well for such interactions. Drawing from examples in the work of my group and our collaborators, I will discuss how robophysical studies have inspired new physics questions in low dimensional dynamical systems (e.g. creation of analog quantum mechanics and gravity systems) and soft matter physics (e.g. emergent capabilities in ensembles of active particles), have been useful to develop insight for biological locomotion in complex terrain (e.g. control targets via optimizing geometric phase), and have begun to aid engineers in the creation of devices that begin to achieve life-like locomotor abilities on and within complex environments (e.g. semi-soft myriapod robots).
Biography: Dr. Daniel I. Goldman is a Dunn Family Professor in the School of Physics at the Georgia Institute of Technology and a Georgia Power Professor of Excellence. Prof. Goldman became a faculty member at Georgia Tech in January 2007. He is an adjunct member of the School of Biology and is a member of the Interdisciplinary Bioengineering Graduate Program.
Prof. Goldman's research program broadly investigates the interaction of biological and physical systems with complex materials like granular media. In particular, he integrates laboratory experiment, computer simulation, and physical and mathematical models to discover principles of movement of a diversity of animals and robots in controlled laboratory substrates.
He received his S.B. in physics at the Massachusetts Institute of Technology in 1994. He received his PhD in Physics in 2002 from the University of Texas at Austin, studying nonlinear dynamics and granular media. From 2003-2007 he did postdoctoral work in the Department of Integrative Biology at UC Berkeley studying locomotion biomechanics.
Prof. Goldman is a Fellow of the American Physical Society (2014), and has received an NSF CAREER/PECASE award, a DARPA Young Faculty Award, a Burroughs Wellcome Fund Career Award at the Scientific Interface, and the UT Austin Outstanding Dissertation in Physics (2002-2003).

Speaker: Megan Leftwich, George Washington University
Talk Title: The Hydrodynamics of Sea Lion Swimming
Abstract: California Sea Lions are highly maneuverable swimmers, capable of generating high thrust and agile turns. Their main propulsive surfaces, the foreflippers, feature multiple degrees of freedom, allowing their use for thrust production (through a downward, sweeping motion referred to as a clap), turning, stability and station holding (underwater hovering). To determine the two-dimensional kinematics of the California sea lion fore flipper during thrust generation, digital, high definition video is obtained using the specimen at the Smithsonian National Zoo in Washington, DC. Single camera videos are analyzed to digitize the flipper during the motions, using 10 points spanning root to tip in each frame. Digitized shapes were then fitted with an empirical function that quantitatively allows for both comparison between different claps and for extracting kinematic data. The resulting function shows a high degree of curvature (with a camber of up to 32%). Analysis of sea lion acceleration from rest shows thrust production in the range of 150-680 N and maximum flipper angular velocity (for rotation about the shoulder joint) as high as 20 rad/s. Analysis of turning maneuvers indicate extreme agility and precision of movement driven by the fore flipper surfaces. This work is being extended to three-dimensions via the addition of a second camera and a sophisticated calibration scheme to create a set of camera-intrinsic properties. Simultaneously, we have developed a robotic sea lion foreflipper to investigate the resulting fluid dynamic structures in a controlled, laboratory setting.

Speaker: Dr. Qiming Wang, USC
Talk Title: Harness Natural Wisdom to Design 3D-Printed Bionic Materials
Abstract: Living creatures are continuous sources of inspiration for designing synthetic materials. However,
living creatures are typically different from synthetic materials in two aspects: First, living creatures typically
feature sophisticated microstructures and architectures that are challenging to reproduce in traditional
engineering practice. Second, living creatures consist of living cells to support their metabolisms, such as
growth, regeneration, and remodeling, which are typically impossible in traditional synthetic materials. In this
talk, by harnessing modern additive manufacturing technologies, dynamic chemistry, and/or living organisms,
we report a series of 3D-printed bionic materials to imitate both architectures and metabolisms of living
creatures. For example, with the aid of dynamic chemistry, 3D-printed lightweight structures can self-heal
large-scale impact damages and fractures. With the aid of living bacteria, 3D-printed polymers can self-grow
into structural composites with pre-designed microstructures. With the aid of living plant cells, 3D-printed
artificial trees can harness photosynthesis to self-remodel into multifunctional materials.
Biography: Qiming Wang is an Assistant Professor in the Department of Civil and
Environmental Engineering of the University of Southern California. Prior to this
position, he received a Postdoc training at Massachusetts Institute of Technology
(2014-2015) and earned his Ph.D. degree at Duke University (2014). His research
interest is centered around additive manufacturing and mechanics of unprecedented
materials and structures that can potentially address grand engineering challenges,
including infrastructure, water, environment, robotics, and healthcare. His research
has been widely reported by prestigious media, such as Science News, Nature News,
Discovery, Washington Post, NBC News, Wall Street Journal, Physics Today,
Materials Today, and NASA Tech Briefs. He received a number of academic awards,
including NSF CAREER (2020), SME Outstanding Young Manufacturing Engineer
(2020), AFOSR YIP (2018), MRS Graduate Student Award (2014), ACS Arthur K.
Doolittle Award, Duke Kewaunee Student Achievement Award (2013), Duke Lew Pre-doctoral Fellowship
(2012), and ASME Best Paper Award (2011). He was elected as the Editor (2018) of ASME Technical
Committee of Mechanics of Soft Materials and become Secretary in 2019, Vice-chair in 2020, and Chair in
2021.

Speaker: Andrew Dorsey, USC AME PhD Student
Talk Title: Design Space Exploration of Future Open Rotors
Abstract: The goal of this paper is to determine whether an open rotor aircraft configuration has the potential to provide fuel-burn benefits relative to a conventional turbofan aircraft, and if so in which regions of the payload range design space adopting an open rotor technology would be most advantageous. A design space exploration focused on the major trends and design drivers is carried out for open rotor aircraft with aft mounted and wing mounted engines, and their performance compared to a turbofan baseline. We consider transport aircraft with ranges between 1000 and 7000 nautical miles and 50 to 400 passengers, and introduce a modeling approach for open rotor engines into a conceptual design and optimization framework. For each range-passenger requirement, aircraft are optimized for minimum fuel burn on an economic range mission. It is found that open rotor configurations are best suited for short range missions with large passenger counts, and that aft mounted open rotors outperfor
m wing mounted ones. The optimum open rotor engine design sacrifices engine and aerodynamic efficiency in order to limit integration penalties and propulsion system weight.
Biography: Andrew Dorsey is a PhD student under Professor Uranga. His research focuses on conceptual aircraft design, aircraft optimization, and exploring future aircraft technologies. Andrew works full time in the Advanced Concepts group of Boeing Commercial Airplanes as a conceptual aircraft designer. He is currently on a rotation supporting 737 MAX Return to Service and 777x Entry into Service. Andrew has a B.S. from the University of Michigan, a M.S. from USC, and is a certified flight instructor.

Talk Title: Pulmonary hypertension assessed using mathematical modeling integrating imaging and time-series data
Abstract: Cardiovascular disease management involves interpreting imaging data, time-series data, and single-valued markers often measured over several visits. While each data type provides insight into the disease state, these snapshots cannot easily be integrated to provide insight into disease predictions. In this talk, we demonstrate how to interpret the disease state using multiscale mathematical modeling integrating computed tomography (CT) images with blood pressure measurements from right heart categorization. We use these models to characterize patient-specific remodeling in the proximal and distal vasculature. We calculate patient-specific nominal parameter values using morphometric and invasively measured hemodynamic data, use sensitivity analysis to determine what parameters best inform the data, and a Bayesian approach to infer identifiable subject-specific parameters and propagate the uncertainty of pressure and flow predictions to all large vessels. We also validate frequency domain results assessing change in wave-propagation and wave-intensity with the disease. For the micro-vasculature, we conduct a morphometric analysis characterizing changes in the arterial networks' branching structure by extracting skeletonized networks from the micro-CT images and using a custom algorithm to represent the network as a connected graph. We determine subject-specific fractal parameters and analyze how these changes with PH. Our model and data analysis outcomes are combined to understand the link between spatially distributed etiologies and global hemodynamics and shed light on the prospect of combining the model and graph-based morphometric analysis of vascular trees.
