ADJUSTABLE DISCRETIZED POPULATION BALANCE FOR GROWTH AND AGGREGATION

The discretized population balance (DPB) of Hounslow et al. (1988) is extended to allow the we of an adjustable discretization of the size d omain of the form v(i+1)/v(i) = 2(1/q) (where q greater than or equal to 1 and is an integer). All the advantages of Hounslow et al's origin al work are retained: the zeroth and third moments of the particle-siz e distribution are correctly predicted and the DPB is simple to solve with no integration within each size interval The predicted and analyt ical particle size distributions are in excellent agreement for the ca ses of nucleation and growth and aggregation alone in batch and in con tinuous vessels. High-order moments and self-preserving particle-size distributions are accurately predicted when q greater than or equal to 4.
