Two-Phase Liquid–Liquid Flow in the Aspect of Reduction of Pumping Power of Hydrophobic Substances with High Viscosity

The paper reports the results of a study into method estimating level power/energy reduction needed for pumping highly viscous hydrophobic liquids. effect reducing flow resistance resulting from feeding an adequate volume water tube is considered. polar parameters selected analysis are different than oil. Experimental studies were not carried out in this regard, since commonly accessible equation expressing two-phase liquid–liquid was utilized to develop discussed study. On its basis, simulations determine conditions and comparison single-phase oily liquid. provided means determination such ranges variations system, which total power pumps applied pump both liquids smaller one oil pipeline flow. Calculations performed constant mass flux densities with various viscosities as well water. proposed can be procedure optimization calculations installations their feed systems. given example use preceded by description reasons effects associated systems detailed presentation how that forms essence described calculation method. Attention also paid other phenomena accompanying flows, i.e., interfacial slip, phase inversion, specific structures, viscosity unstable mixture two flowing pipe.
