HEAT TRANSFER INTENSITY AT FORCED FLOW BOILING OF CRYOGENIC LIQUIDS IN TUBES.

Author(s) : KLIMENKO V. V.

Type of article: Article

Summary

A GENERALIZED CORRELATION FOR HEAT TRANSFER WITH FORCED FLOW BOILING OF CRYOGENIC LIQUIDS (NITROGEN, HYDROGEN AND NEON) IN TUBES IS PRESENTED. THE CORRELATION DESCRIBES, WITH ABOUT 35% ACCURACY, ALL KNOWN EXPERIMENTAL DATA FOR VERTICAL AND HORIZONTAL CHANNELS (WITHOUT STRATIFIED REGIMES) IN THE PRESSURE RANGE 0.9-22 BAR, MASS FLOW RATES FROM 20 TO 2,200 KG/M2.S, AND HEAT FLUXES FROM 400 TO 210,000 W/M2. THE BOUNDARY LINE BETWEEN CHANNELS OF A LARGE AND A SMALL DIAMETER HAS BEEN ESTABLISHED ; A SIMPLE METHOD OF TAKING INTO ACCOUNT THE HIGHER HEAT TRANSFER INTENSITY IN CAPILLARIES HAS BEEN SUGGESTED.
