一、引言 两相临界流研究高温、高压系统破口事故时,汽(气)-液两相流体的最高排放速度,是核电安全中的重要课题。由于两相流动的复杂性,两相临界流理论还没有到成熟阶段。不同试验者的数据,尤其是在低含汽量(x<0.02)时相差较大。
I. Introduction Two-phase Critical Flow The highest discharge rate of gas-liquid two-phase fluid when studying high-temperature and high-pressure system breach accidents is an important issue in nuclear power safety. Due to the complexity of two-phase flow, the theory of two-phase critical flow is not yet mature. The data of different testers differ greatly, especially at low vapor content (x <0.02).
