The effect of gas injection on the protection of body surfaces streamlined by a two-phase flow

Аннотация

The first results of physical simulation of the effect of gas injection on the characteristics of gas stream with solid particles at flow around bodies are presented. The possibility of ensuring an effective protection of the body surface from the negative effects of particles (droplets) is demonstrated. A dimensionless criterion (the Stokes number) is proposed that characterizes the inertia of particles near the critical point of the body and the intensity of their deposition on the surface under injection conditions.
