Calculating Dimensionless parameters for two phase flow is always a tricky part. The majority of experimental publications use the homogenous density and velocity ... this basically because it is easier to measure/calculate. However, when possible, the actual flow parameters are better in comparison. nSo, check the references you are using, if everyone uses the homogenous density, velocity .. you need to follow. If you find discrepancy, do the right thing. n
