BOILING HEAT TRANSFER WITH R11 IN BRAZED ALUMINIUM, PLATE-FIN HEAT EXCHANGERS.

Author(s) : ROBERTSON J. M., LOVEGROVE P. C.

Type of article: Article

Summary

EXPERIMENTS WITH R11 FLOWING IN AN ELECTRICALLY HEATED, SERRATED-FIN TEST SECTION TO MEASURE LOCAL BOILING COEFFICIENTS WITH MASS FLUXES UP TO 150 KG/M2S, HEAT FLUXES TO 4 KW/M2, AND PRESSURE FROM 3-7 BAR, ARE REPORTED. RESULTS ARE COMPARED WITH THE VERY SIMILAR BOILING CHARACTERISTICS, WITH LIQUID NITROGEN AS A TEST FLUID UNDER COMPARABLE FLOW CONDITIONS. THE USE OF A LIQUID-FILM FLOW MODEL TO PRODUCE A NONDIMENSIONAL CORRELATION CONNECTING THE NUSSELT, REYNOLDS, AND PRANDTL NUMBERS OF THE FILM IS DISCUSSED.
