Abstract

In nucleate pool boiling heat transfer of saturated water the wall superheat, orientation of nucleation site etc. affects bubble departure diameter. In this paper, effect of wall superheat in nucleate pool boiling heat transfer on single bubble dynamics using saturated water as a base fluid has been studied experimentally. Single bubble generated using vertical hypodermic tip of needle as a nucleation site. The hypodermic needles were used of inner diameters 0.514 mm with a constant depth of 25 mm having different cross section varying from 300to 900with respect to tip. Single bubble dynamics was studied with the help of PCO high speed camera operating at more than 100 frames per second at atmospheric pressure and at different wall superheat of 4 K to 30 K for constant heat flux.
