Capturing of Shock Wave with Controlling the Numerical Dissipation over a Circular Bump

摘要: In this paper, an efficient blending procedure based on the density-based algorithm is presented to solve compressible Euler equations a non-orthogonal mesh with collocated finite volume formulation. The fluxes of convected quantities including mass flow rate are approximated by using characteristic TVD and ACM Jameson methods. With noticing that different characteristics have diffusion in comparison together, aim present study introduce method variables (Riemann solution) control term classic methods order capture shock waves. Hereby, inviscid supersonic solved results compared together view resolution accuracy waves capturing, solution convergence. Results show good quality wave capturing published density method, while less relative method.
