Stability and turbulence
We are interested in the stability of inertially dominated flows, including interfacial flows, and their potential transition to turbulence. We primarily use direct numerical simulation (DNS) and, to some extent, large-eddy simulation (LES), to investigate turbulent flows, such as compressible turbulence, wall-bounded turbulence and multi-material mixing. We also leverage semi-analytical techniques such as vortex sheet methods.Target applications include energy sciences (high-energy-density physics), aeronautics (aerodynamics, wall-bounded flows), astrophysics.
