The solids volume fraction for 3D systems is calculated according to the method of Hoomans et al [14] 9 ε s = 2 π 3 1 − ε 2 D 3 / 2 The time averaged solid volume fraction in the cell j is ε s j = ∫ t t T o ε s j t d t / T o where εsj t is the instantaneous solids volume fraction of particles in the cell j and To is the time interval
