Modeling of Interfacial Component for Two-Phase Frictional Pressure Gradient at Microscales
A simple approach for calculating the interfacial component of frictional pressure gradient in two-phase flow at microscales is presented. This approach is developed using superposition of three pressure gradients: single-phase liquid, single-phase gas, and interfacial pressure gradient. The propose...

| description | A simple approach for calculating the interfacial component of frictional pressure gradient in two-phase flow at microscales is presented. This approach is developed using superposition of three pressure gradients: single-phase liquid, single-phase gas, and interfacial pressure gradient. The proposed model can be transformed in two different ways: first, two-phase interfacial multiplier for liquid flowing alone ( ϕ l , i 2 ) as a function of two-phase frictional multiplier for liquid flowing alone ( ϕ l 2 ) and the Lockhart-Martinelli parameter, X , and, second, two-phase interfacial multiplier for gas flowing alone (ϕ g , i 2 ) as a function of two-phase frictional multiplier for gas flowing alone (ϕ g 2 ) and the Lockhart-Martinelli parameter, X . This proposed model allows for the interfacial pressure gradient to be easily modeled. Comparisons of the proposed model with experimental data for microchannels and minichannels and existing correlations for both ϕ l and ϕ g versus X are presented. |
