The Impact

The stratified water-oil two—phase flow was modeled using VOF method in horizontal pipe and surface tension was taken into consideration using CSF model. It was found that the surface tension had great impact on the small density difference two-phase flow even in large diameter pipe, which would lead the interface curved and pressure gradient increased.

In present study, the flow patterns of air – water and toluene – water have been investigated experimentally in vertical and horizontal milli channel. The flow regimes were investigated by a high speed video recorder in pipe with diameters of 2 mm. The comprehensive visualization of air - water, two - phase flow in a vertical and horizontal milli channel has been performed to realize the physics of such a two - phase flow. Different flow patterns of toluene – water flow were observed simultaneously in the milli channel at different values of toluene and water flow rates. Consequently, the flow pattern map was proposed for flow in the milli - channel, in terms of superficial velocities of liquid and gas phases.

Effect Of Surface

Improved and novel prediction methods are described for single-phase and two-phase flow of non-Newtonian fluids in pipes. Good predictions are achieved for pressure drop, liquid holdup fraction, and two-phase flow regime. The methods are applicable to any visco-inelastic non-Newtonian fluid and include the effect of surface roughness. The methods utilize a reference fluid for which validated models exist. For single-phase flow, the use of Newtonian and power-law reference fluids are illustrated. For two-phase flow, a Newtonian reference fluid is used. Focus is given to shear-thinning fluids. The approach is theoretically based and is expected to be more accurate for large, high-pressure pipelines than present correlation methods, which are all primarily based on low-pressure, small-diameter pipe experimental data.
