Heat transfer problems with nucleate boiling of liquids

Abstract

Translated fmm Teploenergetika; 19: No. 9, l4-99(1972), Experimental data on and methods for calculating heat transfer coefficients with nucleate boiling of liquids on metallic heating surfaces are discussed with emphasis on the problems created by the effects of the surface conditions of the heating surface. It is concluded that, at the present time, a sufficiently reliable method is available for calculating the mean heat transfer level when boiling normal (nonmetallic) liquids in the region of moderate pressures. However, allowing for the effects of surface conditions remains unsolved and must be further investigated in order to improve the accuracy of design calculations for heat exchangers for thermal and nuclear power plants.
