.... Irregular and breaking waves have been observed for high gas flow rates. Comparisons with wave formation criterion (Jeffrey, 1925) suggest that the sheltering coefficient is a function of the liquid viscosity. Finally, none of the criteria for stratified to non-stratified flow presents a fair agreement...

...-inch (76.2-mm) and 6-inch (152.4-mm) ID. pipes are presented. Experimental and simulation results are compared, and discussions on the effect of both diameter and liquid viscosity on the drift velocity for horizontal flow are made. The results of this work may improve the existing two-phase slug flow...
