【Abstract】 With an oil-gas-water three-phase mixture serving as a working medium a theoretical and experimental study was performed of the average-section void fraction of stratified flows in a horizontal tube. Through a simplified dynamic analysis of the stratified flows a theoretical model was obtained of the section void fraction. The calculated values agree well with experimental ones. It has been found that the factors having an influence on the section void fraction of the stratified flows include not only the reduced gas speed and liquid speed, but also the oil fraction of the oil-water mixture.更多还原
