Figures of experiments conducted to support the numerical analysis of the hydrodynamic mixing characteristics of a rectangular versus a cylindrical mixing crystallizer tank for a membrane distillation apparatus

Clear polycarbonate replicas of the rectangular tanks were manufactured to visually observe the mixing process in the tanks. Silica particles were used to represent the calcium carbonate crystals in the experiment. The data gathered from these experiments showed that the tanks should be operated between 600 to 750 rpm.

The figure names contain the speed of mixing in RPM either 600 or 750 and the time elapsed from the start of agitation. The .1 represents a set of experiments.
