This book was released on 1970 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This study constituted an examination of both nucleate boiling and maximum heat flux characteristics of liquid nitrogen boiling from characterized surfaces. Several textures of gold plated copper surfaces were studied in addition to silver and silver oxide surfaces. Data were taken over a wide range of reduced pressures. All surfaces were examined using a Scanning Electron Microscope (SEM). Data and micrograph comparison revealed that both surface chemistry and surface roughness affect the nucleate boiling characteristics of liquid nitrogen. These effects are separated from each other showing that nucleate boiling is a function of both surface chemistry and topography. Surface roughness was found to have a significant effect on the maximum heat flux with rougher surfaces yielding higher heat flux values. The temperature difference at burnout was found to be a function of both surface chemistry and roughness. Some existing correlations for both nucleate boiling and maximum heat fluxes were examined and shown to inadequately predict the data, primarily because of inability to account for surface roughness and/or surface-fluid interaction as affected by surface chemistry. A maximum temperature difference correlation tested predicted burnout temperature differences well. The necessity to age a surface in the fluid to be boiled was found not to be a result of adsorbed gases, but probably a result of impurities acquired on the surface that must be removed. Attempts to observe hysteresis is were unsuccessful. Hysteresis was found not to be a function of adsorbed inert gases. Data indicated that one mechanism of heat transfer by nucleate boiling will not suffice for all pressures. An existing nucleate boiling correlation was modified to allow for a mechanism change and predicted the data better than other correlations tested"--Abstract, pages ii-iii.

This book was released on 1966 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The object of this investigation was to study the effect of micro-roughness, a thin layer of oil, and infra-red radiations on the cylindrical heat transfer surface of copper, in liquid nitrogen and at atmospheric pressure during nucleate boiling. An attempt was made to find any possible effect of orientation of the heat transfer element on nucleate boiling. A number of different runs were taken with different degrees of roughness, and different orientation positions. Nucleate boiling has been found to be nearly independent of the heat transfer surface roughness and of orientation while strongly dependent on the chemical nature of the surface. Extremely high temperature differences were obtained in the nucleate boiling region by application of a thin layer of oil to the heat transfer surface. Temperature gradients in both the axial direction and the radial direction were found for the surface of the heat transfer element"--Abstract, leaf iii.

Available in PDF, EPUB and Kindle. Book excerpt: Delayed inception of nucleate boiling and patchwise boiling are discussed and the significant parameters restricting the growth of a boiling patch are analytically determined to be: (1) a high nucleate boiling heat transfer coefficient; (2) a low total heat flux; (3) the absence of cavities with a trapped liquid-vapor interface outside the boiling patch; (4) an appropriate value of wall thermal conductivity; (5) a high vapor enthalpy per bubble. A qualitative agreement between theory and experiment was observed for items 1, 2, 3 and 4. A series of pool boiling tests were conducted at one atmosphere of pressure in order to develop a surface finish that would eliminate the observed temperature hysteresis at inception of boiling of liquid nitrogen. The best surface finish developed used a bi-metallic (Zm + Cu) flame spray process. The flame spray and a 0.3-micron-grit polished copper surface were tested for their nucleation properties in forced flow of liquid nitrogen. Visual observations indicated that nucleation occurred promptly on both surfaces at approximately the same wall temperature. (Author).
