RIEMANN PROBLEM FOR THE ONE-VELOCITY
MODEL OF A HETEROGENEOUS MEDIUM

V. S. Surov

UDC 532.529.5

The internal interfractional-interaction forces have been 
allowed for in the one-velocity model of a heterogeneous medium, and 
a complete solution of the Riemann problem has been obtained. The 
shock adiabat of the mixture, consistent with the model's equations, 
has been used in constructing the solution with shock waves.
