Abstract

We consider single-phase gases in which the fundamental derivative is negative over a finite range of pressures and temperatures and show that inadmissible discontinuities give rise to shock splitting. The precise conditions under which splitting occurs are delineated and the formation of the split-shock configuration from smooth initial conditions is described. Specific numerical examples of shock splitting are also provided through use of exact inverse solutions.
