Volume 41, Issue 2 , July 2007, Pages 151-158

https://doi.org/10.22059/jac.2013.7848

Abstract
  This study is about the non-uniform electric field for splitting of water in oil emulsion. If the process occurs in an inhomogeneous electrical field, the drops are polarized and then their mobility is increased. The emulsion drops will be charged and move toward the central point of splitter where the ...  Read More
