BOILING HEAT TRANSFER

Abstract The present paper is devoted to the problem of nucleate boiling heat transfer. Complicated hydrodynamic processes occurring in gas-liquid systems with nucleate boiling have made it impossible up to now to develop a complete theory for this process. A system of differential equations for a nucleate boiling process has been formulated and a rational system of criteria characterizing it has been developed, proceeding from the hypothesis on the hydrodynamic nature of crises in the boiling mechanism. Generalization of experimental works on nucleate boiling has been carried out on the basis of the analysis of some principal problems on the boiling heat transfer theory and a system of hydrodynamic and heat criteria characterizing this process.
