WebAUSM Flux Splitting Details Advection Upstream Splitting Method (AUSM) The Advection Upstream Splitting Method (AUSM) is a method similar in principle to the Van Leer flux splitting already discussed. Here too, the flux is split into two separate components so that each one may be properly upwind stenciled. WebAn alternative way to compute the flux vector appearing in Equation 18.5-6 is by using a flux-vector splitting scheme [ 53].The scheme, called Advection Upstream Splitting Method (AUSM), was first introduced by Liou and Steffen in 1993 [ 202].The AUSM scheme first computes a cell interface Mach number based on the characteristic speeds from the … list of the ten commandments simplified
