Summary

EXPERIMENTS WERE CONDUCTED AT NEARLY AMBIENT PRESSURE UNDER THE CONDITIONS: TUBE INSIDE DIAMETER: 1 AND 3 MILLIMETERS, TUBE LENGTH: 10 TO 100 MM, WATER MASS VELOCITY: 7,000 TO 20,000 KG/M2 S. THE FRICTION PRESSURE DROP RATIO OF SUBCOOLED FLOW BOILING TO NON-HEATING WATER FLOW WAS EXAMINED BY INCREASING THE HEAT FLUX. THE RATIO BEGINS TO INCREASE AT THE HEAT FLUX PROPOSED BY THE SAHA-ZUBER CORRELATION. THE RATIO WAS FURTHER COMPARED WITH THE BERGLES-DORMER CORRELATION. THE TWO-PHASE FRICTION MULTIPLIER OF SUBCOOLED FLOW BOILING WAS EXAMINED ASSUMING THE AHMAD VOID FRACTION AND APPLIE OTE LOCKHART-MARTINELLI CORRELATION. THE ABNORMARITY OF THE SUBCOOLED FLOW BOILING IN 1 MM INSIDE DIAMETER TUBE WAS CONFIRMED. (JSME INT. J., SER. II, JP., 31, N 2, 1988/05, 349.
