Scope of the Variables Determining Aerosol Interaction Forces

1 Scope of the Variables Determining Aerosol Interaction Forces 

The effective force a particle experiences is due to factors both of its constitution and of its environment. 

Particle chemical composition is determined by the specific system being examined. Therefore, it is important to understand when composition may or may not be overlooked in deference to information on particle behavior arising from data collected on different systems. Overall composition is not of itself adequate because particle structure, morphology, and size play important roles. These questions will all be discussed. 

From the foregoing discussion it can be seen that the forces acting upon aerosol particles divide into two categories gas dynamics and chemical physics. In all cases, the former moderates the later to determine the spacial extent of its importance. This chapter will be devoted principally to the chemical physics of aerosol interaction forces (see Chap.2 for discussion of the gas dynamic aspects).
