A sufficient condition for free-stream preserving in the nonlinear conservative finite difference schemes on curvilinear grids
Hongmin Su, Jinsheng Cai, Kun Qu +1
In simulations of compressible flows, the conservative finite difference method (FDM) based on the nonlinear upwind schemes, e.g. WENO5, might violate free-stream preserving (FP),…

Implicit High-Order Gas Kinetic Scheme for Turbulence Simulation
Guiyu Cao, Hongmin Su, Jinxiu Xu +1
In recent years, coupled with traditional turbulence models, the second-order gas-kinetic scheme (GKS) has been used in the turbulent flow simulations. At the same time, high-order…
