An Experimental Study of Nucleate Pool Boiling Heat Transfer from a GEWA-T Finned Surface in Freon-113.

Abstract

A variety of experimental tests were made with a Gewa-T finned surface in Freon-113 to assist in understanding the physical mechanisms which occur during nucleate pool boiling from this type of surface. The influence of the channels between neighboring T-shaped fins was examined with the use of four aluminum shrouds which had top and bottom windows of various apertures, and which were fitted tightly over the Gewa-T surface. The influence of the fins was examined by progressively machining away the fin height to arrive at a smooth cylindrical surface.
