Large-Eddy Simulation of Turbulent Flow in Complex Geometries
These researchers are continuing to develop the computational capability to perform large-eddy simulation (LES) of turbulent flows in realistic engineering geometries. Large-eddy simulation is a computational approach where one filters the unsteady Navier-Stokes equations, and numerically solves for the large-scales while modeling the effect of the smaller scales that have been filtered out. LES has traditionally been restricted to simple geometries. Current research by this group includes: global stability and adjoint sensitivity approaches, jets in crossflow, propeller and rotor acoustics, turbulent cavitation, propeller crashback, particle-turbulence interaction, superhydrophobic surfaces, and fluid-structure interaction.
