Dusty Gas Flow past Bodies under Scattering of Rebounded Particles

Abstract Two-phase gas-particle flow over a flat plate of finite thickness in channel at high subsonic velocity and supersonic transverse past cylinder are considered. The leading edge the is wedge-shaped or represents smooth bluntness constant radius. wedge surface front specified both rough. roughness modeled by two-dimensional profile based on an experiment. Spherical particles mixture form ellipsoids revolution, rectangular prisms, prisms with flat-cut vertices, tetrahedrons parameters each forms vary. impact interaction model proposed earlier consistent experimental data coefficients restitution center-of-mass used to determine translational rotational velocities non-spherical after rebound. Along monosized particles, dispersed phase spread size role studied factors random nature which affect pattern found.
