Modelling and Numerical Simulation of the Flocculation Process

Résumé

The paper deals with a mathematical model and a numerical simulation procedure for the flocculation process, using usual parametrization solutions of the collision frequency and particle fragmentation rate. The results obtained through numerical simulation have shown a high sensitivity of the model with respect to the flocs strength that intervenes in the expression of the fragmentation rate. It has been illustrated the possibility of the flocculation process control through the fluid stirring, that determines the speed gradient that occurs in the expression of the collision frequency.
