Concerning the influence of thermal properties of heating surface material on heat transfer intensity of nucleate pool boiling of liquids including cryogenic ones

Two different points of view exist on the question of how a heating material influences the intensity of nucleate boiling heat transfer. The first is connected with side effects arising from an experimental study of such an influence due to changes of heating surface microirregularity and wetting conditions. The second reason depends on the nature of the relationship being studied because it is the most clearly manifested only for a sufficiently large thickness of heat-conducting walls. Taking these circumstances into account, we have worked out an experimental method enabling trustworthy data to be obtained, which confirm a noticeable influence of thermal properties of a heating surface material on nucleate boiling of cryogenic liquids.
