Type of article: Article

Summary

EXPERIMENTS ON SUBCOOLED FLOW BOILING HEAT TRANSFER ARE CARRIED OUT IN A VERTICAL ANNULAR CHANNEL, THE INNER WALL OF WHICH IS HEATEDAND THE OUTER WALL INSULATED. R113 IS THE WORKING FLUID. FLOW BOILING HEAT TRANSFER DATA ARE REPORTED AT 579, 801 AND 1,102 KG/M2.S, AT 312, 277 AND 243 KILOPASCALS AND 293, 303 AND 309.5 K (20, 30 AND 36.5 DEG C). A MULTIPLE-HYSTERESIS PHENOMENON IS IDENTIFIED. THE MEASURED WALL HEAT TRANSFER COEFFICIENTS ARE COMPARED WITH PREDICTIONS BY VARIOUS CORRELATIONS AND AN IMPROVEMENT OF THE SHAH CORRELATION FOR ANNULI IS SUGGESTED.
