Dimensional Analysis of Electro-Separation Kinetics of Particles from Dielectric Liquids

Article Preview

Abstract:

This paper refers to the purging of particle-dielectric liquid suspensions. The method of treatment of dielectric liquids in electric fields and the physical quantities involved in the process is presented. In order to determine the dimensionless numbers involved in the electroseparation process a dimensional analysis is made with the purpose to obtain an equation that expresses the efficiency of the electroseparation process depending on the physical quantities involved in it. To simulate the dependence of particles relative concentration and the processing relative time on other similarity criteria was developed a calculation software program in Mathcad 14.
