Calculation of pressure loss for two phase flow in a horizontal or vertical straight pipe for an overall flow regime considering frictional, momentum and geodetic pressure loss.

Generally the pressure loss for two phase flow in a horizontal or a vertical straight pipe can be calculated for the following fluid flow regimes:

Horizontal fluid flow [(a) bubble flow, (b) stratified flow, (c) wavy flow, (d) slug flow, (e) annular flow]:

twoPhaseFlowRegimes_horizontal

Vertical fluid flow [(a) bubble flow, (b) plug slug flow, (c) foam flow, (d) annular streak flow, (e) annular flow]:

twoPhaseFlowRegimes_vertical
