Two dimensional Riemann-type problem and shock diffraction for the Chaplygin gas
Applied Mathematics Letters(2020)
摘要
We are concerned with the two-dimensional Riemann-type problems of the isentropic Euler system for the Chaplygin gas with initial data being two constant states outside a convex cornered wedge. We establish a global theory of existence of self-similar solution. Our results on shock intersections can be applied to solve the shock diffraction problem.
