Bubble flow regime map
WebNote that both show well-mixed regimes occuring above some critical liquid flux and above some critical gas flux; we expand further on this in section 7.3.1. Figure 7.1. Flow … WebFor oil-water mixtures, the most common regimes are bubble flow, slug flow and emulsion flow. In horizontal wells, there may be stratified or wavy stratified flow in addition to many of the regimes observed in vertical wells.
