DROPLET BREAK-UP THROUGH AN OBLIQUE SHOCK-WAVE

The interaction of a two-phase flow with a wedge where a stationary sh ock wave is initially settled is studied in a two-dimensional configur ation. Before the introduction of the dispersed phase, the how around the wedge is a supersonic one phase flow such as an attached stationar y shock wave is present. Then, the dispersed phase is introduced upstr eam 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 g as phase equations and also for the dispersed phase equations wich is an original approach due to the authors (Saurel et al, 1994). In addit ion to drag forces and heat and mass transfers, the process of droplet s fragentation based on the particle oscillation is considered.
