NUMERICAL METHOD FOR SOLVING THE TWO-DIMENSIONAL RIEMANN PROBLEM TO SIMULATE INVISCID SUBSONIC FLOWS

摘要

This invention relates to the numerical method for simulating inviscid subsonic flows by solving two-dimensional Riemann problem. this invention transforms the Euler equations into a stream-function plane and solve the equations under an uniform computing grid by solving the two-dimensional Riemann problem across streamlines and the two-dimensional Riemann problem along streamlines.
