截面含气率
Experimental and theoretical studies were carried out to investigate the characteristics of flow pattern, void fraction and frictional pressure drop of gas-water flow in horizontal transparent tubes under rolling state, the inner diameter of which was 25mm and 34.5mm respectively.
本文主要通过实验研究和理论分析,对管径分别为34.5mm和25mm水平布置的透明有机玻璃管内气-水两相流在摇摆状态下的流型、截面含气率以及摩擦压降进行了研究。
空隙率
When the aspect ratio is 1.0,the void fraction distribution does not affect the pressure variation and the structure is stability. Whereas,if the aspect ratio is in the range from 1.5 to 2.0,the structure is unstable when the pressure increases.
结果表明:该方法适合用于气液两相流空隙率的测量,在纵横比为1.0时,气泡羽流的结构受压强影响小,羽流结构稳定;纵横比为1.5和2.0时,随着压强的增大,羽流结构呈现不稳定。
