Critical Heat Fluxes for Curved and Straight Surfaces during Subcooled Flow Boiling

Abstract

Experimental and analytical studies of the critical heat flux for subcooled flows of Freon 113 over concave, convex and straight surfaces have been conducted. Correlation functions for the critical heat flux on each surface have been developed from an idealized model of the vapor bubble cycle in nucleate boiling. These functions have been evaluated and compared with data collected in an experimental apparatus, constructed as part of this investigation. Details of the apparatus design and operating procedures are given.
