The two-fluid flow is produced by the combined effects of electroosmotic force in a conducting liquid and pressure gradient force in a non-conducting liquid. The Poisson-Boltzmann and Navier-Stokes equations are solved analytically; and the effects of governing parameters are examined. Poiseuille number increases with increasing the parameters involved. In the absence of pressure gradient, the ...

A novel method of combined argon gas stirring and bottom-rotating electromagnetic stirring in a ladle refining process is presented in this report. A three-dimensional numerical model was adopted to investigate its effect on improving flow field, eliminating temperature stratification, and homogenizing concentration distribution. The results show that the electromagnetic force has a tendency to...

A set of two phase flow experiments for conditions ranging from bubbly flow to cap/slug flow have been performed under isothermal concurrent air-water flow conditions in a vertical column of 3 m height. Also the liquid properties like the surface tension have varied by adding small quantities of 1-Butanol in order to see how these changes affect to the two phase flow properties. Numerical simul...
