On the collision Between Small Particles and a Plane Wall in a Jet

Abstract

When a jet stream containing the small particles impinges on a plane wall, the particles are possible to collide with the wall. Under the assumption that the flow is incompressible and irrotational, the fluid is governed by stokes drag law, and the interaction between particles is neglected, the classification of various types in the collision between the particles and the wall, the critical conditions above which the particles collide with the wall, the extent of the region in which the collision arise, the distribution of the collision frequency along the wall, the ratio of collision particles to total of particles, the position at which the collision frequency becomes maximum and so on are found theoretically by choosing the stokes number and the angle between the axis of the jet and the wall as the parameters.
