Title: Numerical studies to the Chaplygin gas system and Pressureless Euler Equations
Speaker: Ying Wang
University of Oklahoma, USA
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.
