Numerical Simulation to Study Riemann Problem for Euler Equations in Case of Two Supersonic Flows Collide

In this work we run numerical simulation of gasdynamic to study Riemann problem for the case of collision between two supersonic flows. We analyzed the profiles of density, velocity, pressure, furthermore we inspect for the late time the Mach number which is represent the shock strengths, the specific internal energy density, the total energy density, and the entropy related quantity. Our results reveal that the collision between two supersonic flows leads to the formation of two shocks separated by a contact discontinuity, as well as the numerical results for Euler equations and the exact solution are close to each other
