ENTROPY JUMP ACROSS AN INVISCID SHOCK-WAVE

The Shock jump conditions for the Euler equations in their primitive f orm are derived by using generalized functions. The shock profiles for specific volume, speed, and pressure and shown to be the same, howeve r, density has a different shock profile. Careful study of the equatio ns that govern the entropy shows that the inviscid entropy profile has a local maximum within the shock layer. We demonstrate that because o f this phenomenon, the entropy propagation equation cannot be used as a conservation law.
