Abstract: | The interaction of a two-phase flow with a
wedge where a stationary shock wave is initially settled is studied
in a two-dimensional configuration. Before the introduction of
the dispersed phase, the flow around the wedge is a supersonic
one phase flow such as an attached stationary shock wave is
present. Then, the dispersed phase is introduced upstream the
initial position of the stationary shock wave. The purpose of
this study is to point out two-phase and droplets break-up
effects on the oblique shock wave. The two-dimensional
equations are solved by a TVD scheme where fluxes are computed
by using Riemann solver for the gas phase equations and also
for the dispersed phase equations wich is an original approach
due to the authors (Saurel et al. 1994). In addition to drag
forces and heat and mass transfers, the process of droplets
fragmentation based on the particle oscillation is considered.
