Résumé

Investigation results of the process mechanism and intensity of heat transfer at subcooled water boiling are presented. Vapour bubbles dimensions dmax, their generation frequency f and the cycle average growth rate w"=dmax·f are determined. At the same subcooling and pressures the values of boiling heat transfer coefficients α are defined. Relationships between w" and α are stated. As a result of investigation the process peculiarities are cleared up and the design criterional equation for determination of α at pool boiling of subcooled water is grounded.
