..., this study investigated and analyzed the dimensionless numbers to deal with the huge difference of gas densities (pressure) between experiments and gas wells for pressure scaling up. And then we proposed a new simple empirical model of liquid holdup based on the experimental tests. Figure 1 Churn flow...
