63rd NIA CFD Seminar
Topic: High-Fidelity Simulations of Complex High-Speed Flows
Date: Tuesday, September 15, 2015
Time: 11:00am-noon (EST)
Room: NIA, Rm137
Speaker: Ali Uzun
Speaker Bio: Dr. Ali Uzun recently joined NIA as a Senior Research Scientist. He received his Ph.D. in Aeronautics & Astronautics from Purdue University in 2003. He joined the Florida State University as a post-doctoral research associate immediately after completing his Ph.D. and later became a Research Scientist at the Florida Center for Advanced Aero-Propulsion, Florida State University. His current research interests include computational fluid dynamics using high-order numerical methods, turbulence simulations, computational aeroacoustics and parallel computing.
Abstract: This talk will present sample applications of high-fidelity numerical simulations to complex problems that contain high-speed flow phenomena. Example applications include prediction of noise generated by high-speed free/impinging jets and detailed simulation of resonance-enhanced micro-actuators that generate pulsed high-momentum supersonic micro-jets for flow/noise control applications. A large eddy simulation (LES) methodology based on high-fidelity numerical schemes developed for turbulence simulations and computational aeroacoustics (CAA) has been utilized to perform the large-scale simulations. This talk will provide an overview of the numerical methods implemented in the simulation methodology and present representative results from the calculations. Comparisons with available experimental measurements will be made to assess the predictive capability of the simulations.
