Computational Studies of High-Speed Shear Flows
Shear flows occur in many fluid mechanics applications ranging from incompressible subsonic flows to compressible hypersonic flows, such as boundary layer flows developing overground, submersible or airborne vehicles, jet flows emitted by aircraft engines or rocket nozzles, or wakes generated by blunt objects moving through air or water. In this talk, our previous and current efforts aimed at computationally analyzing and controlling various shear flows, in an attempt to reduce the frictional drag force of alter the heat transfer, are presented and discussed. The primary mathematical model is represented by the Navier-Stokesequations, describing the motion of a non-Newtonian viscous fluid, which are discretized and solved in the framework of large eddy simulations or non linear boundary region equations. The talk will cover computational fluid dynamics applications in areas such as high-speed jet flows, boundary layers and free mixing layers, as well as the application of a robust nonlinear optimal control strategy targeting the reduction of the frictional drag in high-speed boundary layers.
Biography
Adrian Sescu is currently an Associate Professor and Graduate Coordinator in the Department of Aerospace Engineering, Mississippi State University. He is also affiliated with High-Performance Computing Collaboratory (HPCC), a coalition of MSU member institutes and centers, where he serves as the Graduate Coordinator for the Computational Engineering Program.He has been a postdoctoral associate in the Turbulence Research Group of the Department of Mechanical Engineering, Johns Hopkins University, and multiple times affiliated with Air Force Research Lab. He received his PhD degree in Mechanical Engineering from the University of Toledo, and his MS and BS degrees in Aerospace Engineering from the Polytechnic University of Bucharest. His research interests cover topics in boundary layer transition and control, aero acoustics, and turbulence in fluids, which resulted in the publication of over 90 journal articles and conference proceedings in these areas. He is an Associate Fellow of the American Institute of Aeronautics and Astronautics, and active in various committees under the American Physical Society, Division of Fluid Dynamics.
