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.

The researchers are working on several projects that utilize and further develop this simulation capability: jets in crossflow; propulsor crashback; turbulent combustion; hypersonic transition; shock wave/boundary layer interaction; and turbulent bubbly flows.
