Adhesion of Particles in an Air Stream

Abstract

Relationships in Adhesive Interaction In an Air Stream. The adhesion of particles of different sizes to surfaces located in the path of an air stream will be determined by the particle size and velocity and the particular features of movement of the dust. The adhesion of particles from the stream is possible if such forces arise so that particles cannot be removed from the surface (see Chapter IV) but the primary conditions governing adhesion are the approach of the particle to the surface and the contact time between particle and surface. In this section, as in the following sections of this chapter, we are not concerned with the particular features of particle motion at the surface, but rather we will sort out the conditions that tend to hinder or favor contact of the particles with the substrate and hence affect adhesion.
