| Abstract: | A numerical analysis has been made of laminar stratified flow of two immiscible Newtonian liquids in circular and certain non-circular pipe configurations. Solutions are given far viscosity ratios of 10, 100, and 1000 and for various volumetric flow rate fractions. Five pipe configurations are studied. In each case volumetric flow rate factors and power reduction factors are computed. It is shown that the circular pipe is the best pipe configuration for the two-phase flow having a viscosity ratio of about 10 or less. A flat bottomed pipe configuration is found to give higher volumetric flow rate factors as well as higher power reduction factors than the circular pipe when the viscosity ratio is about 100 or more. |
