Heat Transfer in Boiling of Liquid Films
RÉSUMÉ
The work is devoted to the heat transfer in boiling of films of various liquids formed by wetting a heat generating surface from a sprayer in the form of a capillary tube. A physical model of the incipience of a vapor phase in thin layers of liquid in the absence of thermal gravitational convection is presented and on its basis a computational relation is given for the temperature head in boiling-up ΔTs.b.. An interpolation dependence of ΔTs.b. on the height of the column (layer thickness) of liquid on a heat generating surface is suggested which makes it possible to estimate this parameter in the layers of liquid in which there is nondeveloped gravitational convection.
