    Talk Title: Passive and Active Control of Turbulent Jets and Flames -” A CFD Research

    Abstract: Interest in flow control techniques is driven by a possible improvement of performance, safety and efficiency of various technical devices. Existing strategies of steering and controlling fluid flows can be divided into two approaches: passive and active. The former is based on shaping the flow domains and is usually optimized for specific flow conditions. The latter requires an external energy input (an excitation, forcing), which can be varying in response to the instantaneous flow behavior. The active methods are thus more costly but also much more flexible. Under a variety of different flow regimes, they result in a better overall response than the passive methods. In this talk, I will focus on the CFD study of passive and active control applications for jets and flames. In the latter case, proper flow control is especially important as the efficiency of combustion processes is directly related to fuel-oxidizer mixing -” a process, which we would like to have under full control. I will discuss to what extent the flow field can be modified and controlled by the selection of shapes of jet nozzles or tuning of excitation parameters.

    Biography: Artur Tyliszczak is a Professor in the Faculty of Mechanical Engineering and Computer Science at Częstochowa University of Technology (CUT) in Poland. He leads the CFD Research Group. He earned an M.S. degree in Mechanical Engineering in 1997 from the CUT and a PhD degree in 2002 from the CUT and von Karman Institute for Fluid Dynamics (Belgium). He worked at Cambridge University (UK) as a Marie-Curie Experienced Researcher (2010-2011) and a visiting professor (2016). His group works on the development of high-order numerical methods for CFD and their applications for open and near-wall non-reacting and reacting flows. Currently, his main research concentrates on passive and active flow control in jet type flows and flows in porous and granular layers. Artur Tyliszczak is a recipient of prestigious individual awards from the Polish scientific community, the Ministry of Science and Education, the Polish Academy of Science, the Polish Association of Theoretical and Applied Mechanics. Recently he received a Senior Award from the Fulbright Commission for his stay at USC.
