STOCHASTIC SIMULATION OF PARTICULATE DYNAMIC BREAKUP

Based on the analysis of dynamic breakup process of particles in parti culate systems, a direct stochastic simulation method is proposed in t his paper, which is applicable for general population balances with pa rticle breakup. The detailed algorithm is presented. There are two imp ortant steps in algorithm: 1. to determine whether a particle breaks u p, using the breakup frequency function; 2. to determine the volume of daughter particles for one breakup, using the probability distributio n function of daughter particles after the breakup of a mother particl e. A calculation example of turbulent liquid-liquid dispersion is give n to predict the development of particle size distribution. The calcul ation results are in very good agreement with the analytical solution from Das (1996).
