"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, page iii.
