This book presents the analysis of fundamental achievements and the unique results of original studies of various researchers in the field of boiling processes. It shows that boiling heat transfer and critical heat flux depend on physical properties of both liquid and heat releasing surfaces, as well as their geometric parameters. It should serve as the basis for developing a numerical solution to the problem describing the most complex mechanism of heat transfer during boiling. The calculation algorithms given here also allow the development of computational programs aimed at optimizing the weight, dimensions, and cost of the designed heat transfer equipment. As such, the book will be useful for specialists dealing with cryogenic and refrigeration technology, oil refining, and nuclear and space technology.
