A low numerical dissipation patch-based adaptive mesh refinement method for large-eddy simulation of compressible flows

This paper presents a hybrid finite-difference/weighted essentially non-oscillatory (WENO) method for large-eddy simulation of compressible flows with low-numerical dissipation schemes and structured adaptive mesh refinement (SAMR). A conservative flux-based approach is described, encompassing the cases of scheme alternation and internal mesh interfaces resulting from SAMR. An explicit centered scheme is used in turbulent flow regions while a WENO scheme is employed to capture shocks. Several one, two, and three-dimensional numerical experiments and validation calculations are presented including homogeneous shock-free turbulence, a turbulent jet and the strongly shock-driven mixing of a Richtmyer-Meshkov instability.
