IMPINGEMENT MIXING - A FLUID MECHANICAL APPROACH.

This study is presented in order to understand the process in a fundamental way. Such knowledge should prove useful in the design and scale-up of equipment, and also in approaching new problems such as the reaction molding of reinforced materials. It is found that the mixing quality of an impingement mixer increases continuously with increasing Reynolds Number and decreases with increasing mixer size. Momentum ratio appears to have very little effect on mixing quality when the fluid delivery scheme does not permit crossfeed. A simple theory based on dimensional analysis and the Kolmogoroff micro-scale with Reynolds Number. Experimental data are in good agreement with the theory.
