A conjugate solution has been obtained for ascending cocurrent turbulent gas flow and laminar liquid wavy film flow in an inclined flat channel without drop entrainment. The waves have been represented as surface roughness features. Experimental studies have been conducted for air-water, air-diethylene glycol, and air-aqueous sucrose systems, and the results have been compared with the calculated data.
Получено сопряженное решение для газового турбулентного потока и жидкой ламинарной волновой пленки при восходящем прямотоке без брызгоуноса в плоском наклонном канале. Использована модель представления волн как шероховатостей. Проведены экспериментальные исследования и сопоставление с ними результатов расчетов для систем воздухвода, воздухдиэтиленгликоль, воздухводный раствор сахарозы.
A model of interaction of a gas stream with a film of fluid moving in the laminar wave regime based on representation of waves as roughness is proposed. It allows calculating hydraulic resistance of a pipe, average thickness of a film, shear stress on the boundary separating phases, velocity field and a number of other characteristics. Adequacy of the model is demonstrated by comparison with open literature experimental data in a vertical pipe.
