Boundary conditions for the equations of fluid mechanics of the solid phase of a gas suspension
Abstract
The interaction between the particles of a gas suspension and the surface of a solid body is described in terms of surface roughness and nonabsolute elasticity. A wellknown method from the kinetic theory of gases is used to obtain boundary conditions for the equations of fluid mechanics describing a weakly nonequilibrium flow of the disperse phase of a gas suspension with rotating particles. A surface effect criterion, a dimensionless parameter characterizing the effect of particlesurface collisions on gassuspension flow past a body, is formulated.
