![عکس صفحه اول مقاله: A low numerical dissipation patch-based adaptive mesh refinement method for large-eddy simulation of compressible flows A low numerical dissipation patch-based adaptive mesh refinement method for large-eddy simulation of compressible flows](/preview/png/522691.png)
We present a methodology for the large-eddy simulation of compressible flows with a low-numerical dissipation scheme and structured adaptive mesh refinement (SAMR). A description of a conservative, flux-based hybrid numerical method that uses both centered finite-difference and a weighted essentially non-oscillatory (WENO) scheme is given, encompassing the cases of scheme alternation and internal mesh interfaces resulting from SAMR. In this method, the centered scheme is used in turbulent flow regions while WENO is employed to capture shocks. One-, two- and three-dimensional numerical experiments and example simulations are presented including homogeneous shock-free turbulence, a turbulent jet and the strongly shock-driven mixing of a Richtmyer–Meshkov instability.
