Abstract

Interaction of a shock wave and a
motionless combined discontinuity
separating two two-component mixtures
with different initial volume
concentrations is studied on the basis
of numerical simulation of unsteady
processes. The calculations were
performed using a modified method of
"coarse particles" and a high-accuracy
TVD difference scheme adapted to
calculation of two-phase flows. Flow
parameters determined by analytical
dependences coincide with those obtained
by numerical simulation at large times
of the process. Upon interaction of the
shock wave and the combined
discontinuity, the type of the transient
or reflected shock wave may coincide
with or differ from the type of the
incident shock wave. The possibility of
existence of a pressure difference at
the combined discontinuity boundary,
which was earlier predicted
analytically, is confirmed.
