Background
Professor Lele's research combines numerical simulations with analytical modeling to study fundamental unsteady flow phenomena, turbulence, flow instabilities, and flow-generated sound. Recent projects include simulation and modeling of high-speed jets and shock-cell noise, exploitation of flow instabilities for enhanced mixing and for reducing the vortex-wake hazard from an airplane, new approaches for active/passive noise control, and the development of high-fidelity prediction methods for engineering applications including transition and flow-generated noise. Professor Lele has a joint appointment in the Department of Mechanical Engineering and in the Department of Aeronautics and Astronautics. He has been an Associate Editor of the Journal of Fluid Mechanics since 1994.
