Talk Title: From Beating Hearts to Buzzing Wings: Flow Physics and Computation at the Intersection of Mechanics and Bioengineering

Abstract: The unceasing growth in computational power and the development of new software tools and numerical algorithms is opening up exciting areas of research, discovery and translation in mechanics and biomedical engineering. Consider the mammalian heart, which has been sculpted by millions of years of evolution into a flow pump par excellence. During the typical lifetime of a human, the heart will beat over three billion times and pump enough blood to fill over sixty Olympic sized swimming pools. Each of these billions of cardiac cycles is itself a manifestation of a complex and elegant interplay between several distinct physical domains including electrophysiology, muscle mechanics, hemodynamics, flow induced valves dynamics, acoustics, and biochemistry. Computational models provide the ability to explore such multi-physics problems with unprecedented fidelity and precision. In my talk, I will describe several projects that demonstrate the application of powerful computational tools to problems ranging from chemo fluidics of clot formation to fluid structure interaction in prosthetic heart valves. The talk will culminate with a brief discussion on a new project where we are using computational aeroacoustics to analyze wing tone based communication in mosquitoes.
