Abstract

In this talk, we will discuss the numerical solutions to the Riemann problem for Chaplygin gas equation, which is the Euler equations equipped with the state equation p = -1/\rho, as well as the 2D zero-pressure Euler Equations. The spatial discretization is performed using WENO reconstruction together with a carefully defined limiter and time integration is achieved using TVD RK. The numerical results confirm high order of accuracy. This is a joint work with Ling Jin.
