Experimental Investigation of pressure drop in concurrent air-water flow

Pressure drop measurements for horizontal stratified two-phase flow of air water have been performed in a channel with 5.33m length, 0.20m width, and 0.1m height. The gas and liquid Reynolds numbers were varied in the 54000-87000 and 13000-23000 ranges, respectively. A correlation was proposed for predicting pressure drop in horizontal stratified two phase flow. Predictions of the correlation proposed in this work were compared with experimental data and showed much better agreement compared to Friedel equation.
