主　　题：critical flow thermal nonequilibrium sharp-edged tubes. 

摘      要：The transient critical flow experiment with sharp-edged tubes as the break geometries is conducted in high pressure convective circulation test loop of Xi an Jiaotong University. The initial steady operation pressure is up to ***. An empirical correlation was made to obtain the critical mass flow rates, the critical pressure ratio and the thermal nonequilibrium number were correlated as the functions of the tube length to tube diameter ratio L/D. The predicted critical mass now rate gets a higher accuracy for short tubes with L/D 12.
