mass velocity

The effects of pressure, mass velocity, inlet subcooling, heat flux, and exit throttle on the flow instability were determined in the modeling experiment. The thresholds of the flow pattern transformation instability and that of the density wave instability were obtained.

通过模型试验确定了压力、质量流速、入口过冷度、热流密度、出口节流阻力等因素对不稳定性的影响，得出了流型转化型和密度波型不稳定性的界限。

Correlation of critical mass velocity has been provided.

文中还给出了临界质量流速的试验关联式。

Compared with the results of LSC, the heat transfer coefficient of LSC was lower than those of them at low mass velocity, but higher at high mass velocity.

与汽液分离式冷凝器的结果相比，在低质量流速下汽液分离式冷凝器的传热系数低于两者，但在高流速下高于两者。
