【摘要】 通过对低压下不同工况系统实验研究，总结了包括系统压力、进口过冷度、加热段进出口阻力、加热段管径等对流动不稳定的影响，并对实验数据进行了综合，得出了一个无量纲关系式。更多还原

【Abstract】 The effects of parameters on two- phase natural circulation flow instability are imPOrtant in mechanismic analysis, theoretical study, and modelling investigation. This paper makes an systematic study of various factors through a series of experiments under low pressure conditions. These parameters include system pressure, inlet subcooling, outlet resistence, heater pipe diameter. Through detailed analyses a non- dimensional correlation is obtained which agrees well with the experimental data.更多还原
