The effects of floc porosity change during the process of their formation are examined using numerical solutions of Population Balance equation under Brownian coagulation.
According to the numerical experiments. the following results were nhtaineri
1) In the range represented by straight line on the Rosin-Rammler' diagram based on the weight of floc constituents, the distribution constants in both cases of Droplet model and Model 2 were seemed to he constant d urine the process of coagulation. And the distribution curves of Model 1 were represented by the combined straight lines on the diagram.
2) The decrease in number of floc during coagulation could be fitted by a second -order kinetic expression. The rate constant of Droplet model without porosity was smallest, and that of Model 2 was less than that of Model 1. These results show the effect of floc porosity change through their formation
3) When the tloc porosity is changeable during coagulation, the self-preserving spectra could be obtained by using the new similarity variables based on the weight of floc constituents.
