... Abstract Heavy oil production and transport remains a challenge due to the lack of understanding of the flow behavior of gas and high viscosity oil two-phase flow in pipes. For example, existing two-phase flow in pipes mechanistic models shows significant discrepancy in predicting high-liquid...

.... 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...
