... flows. It is challenging to quantify the effects of density, viscosity and surface tension without affecting any of the other parameters (6). Nonetheless, numerical simulation can play a powerful role to analyze viscosity stratified flows. In the last decade, the research emphasis in two phase flow has...

... of on the liquid superficial velocity The second characteristic length scale that may be obtained from dimensional analysis is = which represents surface tension forces. In this case the corresponding generic roughness becomes = which in combination with equation (7) gives 1 = 2log We (12) where...
