19.1.4. Total and Average Geometric Properties of a Particle Population

Similarly, the total particle volume is found to be

(19–8)

where [g/cm3 ] is the bulk density of the particle core. By assuming that the particles are spherical, an average particle diameter can be obtained as

(19–9)

The total sphere-equivalent surface area of a particle population is given as

(19–10)

With these equations, all basic properties of a particle population are defined for the moment method. In Particle Coagulation through Particle Transport Equations , we introduce the kinetics models used by the Particle Tracking feature to describe formation, growth, reduction, and interaction of the particles.
