An Experimental Investigation of the Effect of Surface Conditions on Nucleate Pool Boiling Heat Transfer to Liquid Nitrogen from a Horizontal Surface

Pages : 86
Book Description
A system was designed to investigate experimentally the mechanism of nucleate pool boiling heat transfer using commercial grade liquid nitrogen as a working fluid. A circular horizontal flat plate five square centimeters in area was utilized as a boiler surface. The effect of various surface parameters on the characteristic heat flux versus (Tw-Ts) curve at atmospheric conditions was determined. Surfaces used included a highly polished mirror surface, a mirror surface coated with oxide, a mirror surface coated with grease, a roughened surface, and a roughened surface coated with Teflon, all fabricated from commercial electrical tough pitch copper. The final surface used was a Nickel 200 highly polished mirror surface. The data from the copper surface with a mirror finish was in agreement with the data of previous investigations. The effects of roughness, contaminants, hysteresis, and boiler surface material were discussed. A comparison was made on incipient boiling heat fluxes. The results indicate that the surface conditions play a major role in nucleate pool boiling heat transfer to liquid nitrogen.

An Analytical and Experimental Study of the Thermal Boundary Layer and Ebullition Cycle in Nucleate Boiling
Author: Yih-Yun Hsu
Publisher:
ISBN:
Category : Ebullition
Languages : en
Pages : 54
Book Description
The ebullition cycle of nucleate pool boiling from a heating strip was studied through the use of high-speed motion pictures of schlieren and shadowgraph images. The effects of bubble agitation on thermal layer and neighboring bubbles were observed. An over-all model of ebullition based upon experimental observation was proposed that included an analytical method for predicting bubble growth rate and an analysis of the factors that influence the magnitude of the waiting period (time interval between bubbles at a particular site). Thermal-layer thickness, cavity size, and area of influence of a growing bubble are considered. A film supplement is made available. (Author).
