Boiling Heat Transfer to Liquid Hydrogen from Flat Surfaces
The object of this paper is to present and briefly discuss the experimental data obtained for the transfer of heat to boiling hydrogen from a relatively large flat surface under a variety of conditions. These conditions include the angle of orientation of the surface, surface condition, and hydrogen pressure. The effect of vertical height of the heating surface was also noted. A limited amount of experimental data can be found in the literature on heat transfer to boiling hydrogen, but the results are not in close agreement. In almost every case a very small heater was used and the effects of a number of variables were not investigated [1–3], Although the experimental data bracketed data obtained by theoretical correlations, it was not possible to determine which experimental data were more accurate.
