HYBRID CONTINUOUS TIME-MONTE CARLO SIMULATION OF DISPERSE SYSTEMS

A hybrid continuous time-Monte Carlo method for solution of equations of a detailed population balance model is presented for two phase disperse systems perfectly mixed on macrolevel. The dispersed phase is described by a population balance equation including aggregation or coalescence and breakage of particles, as well as collision induced exchange of mass of species and heat between the particles. The resulted population balance equation is solved by coupling the deterministic continuous time computation of heat and mass balances and chemical reactions with the random discrete time events of particles population using Monte Carlo simulation. Applicability of the method is illustrated by simulation of a suspension polymerization reactor and a continuous stirred tank coalescence/redispersion reactor.
