A Low-Numerical Dissipation, Patch-Based Adaptive-Mesh-Refinement Method for Large-Eddy Simulation of Compressible Flows
This paper presents a hybrid finite-difference method for the large-eddy simulation of compressible flows with low-numerical dissipation and structured adaptive mesh refinement (SAMR). A conservative flux-based approach is described. An explicit centered scheme is used in turbulent flow regions while a weighted essentially non-oscillatory (WENO) scheme is employed to capture shocks. Several two- and three-dimensional numerical experiments and validation calculations are presented including homogeneous shock-free turbulence, turbulent jets and the strongly shockdriven mixing of a Richtmyer-Meshkov instability.
