Chapter 5 - THE BEHAVIOR OF A SINGLE PARTICLE

Abstract

Solid particles or droplets in the continuous phase, undergoing a chemical or a physical change, are the major constituents in systems employing impinging streams (IS). The motion of a gas particle suspension in IS is very complicated. The chapter discusses the behavior of a single particle and its interaction with the continuous phase. It yields simple equations and results for system design. Such results are applicable for dilute suspensions, where collisionless flow may also be assumed. The chapter also discusses the motion of a single particle in the absence of a gravitational force. This case is applicable to horizontal flow of the particle, where analytical solutions for important parameters are also derived. Other cases examined are the flow of a particle at some inclination in regard to the horizontal and the vertical flow of a particle. The gravitational forces are effective in these cases; however, the solutions for various flow parameters are numerical.
