where CDP is the average drag coefficient for a single particle in a suspension. In the frame of a kinetic theory, the particle-particle collision time can be written:

where 0s is the granular temperature and go is a distribution function defined in Section 4.2.2. Particle response time is defined as

P2dp 18^i
