Abstract
Many aerosol measurement techniques are based on the behavior of ideal aerosol particles, that is, spherical particles with a density close to 1000 kg/m3 [1 g/cm3]. In dealing with most real-world particles, allowances must be made for nonspherical particle behavior. In many situations, nonideal particle behavior or property can be considered as a modification of ideal particle behavior by using a correction factor, commonly called the shape factor. Two types of particles, agglomerates (or clusters of particles) and fibers, have been dealt with extensively in the literature and are discussed in more detail in this chapter.
