When I use conservation formulation of Euler equations to solve inviscid flow about expansion corner at mach >>1, I face a problem of internal energy goes to negative value. This means that kinetic energy more than the total energy. Any help to solve this problem or any online material related to this problem. Thanks in advance cfd student.
