Abstract
The problem of interaction of shock
waves of various types (completely
dispersed, frozen-dispersed, dispersed-
frozen, and frozen shock waves with a
two-front configuration) with a
motionless combined discontinuity in a
mixture of two condensed materials is
considered. The mathematical description
is based on the equations of mechanics
of heterogeneous media in a one-
dimensional isothermal approximation
with allowance for differences in
velocities and pressures of the
components. In the equilibrium
approximation in terms of velocities and
pressures of the components, the wave
configuration and flow parameters are
determined in all equilibrium states
behind the incident, transient, and
reflected shock waves.
