BOILING AND BUBBLING HEAT TRANSFER UNDER THE CONDITIONS OF FREE AND FORCED CONVECTION
The present paper gives the main results of studying the hydrogasdynamic aspects of heat transfer and blow-off effect at the developed nucleate boiling by analogy with bubbling under the conditions of free convection. For the first time it proved possible to detect the explicit influence of gas (vapour) phase compressibility on the heat transfer intensity and the effect of liquid blow-off from the surface of heating (bubbling). The existence of regimes automodel with respect to liquid phase viscosity has been found.
A description is given of the first forced-circulation loop to study heat transfer and blow-off effect at forced gas-liquid flow in tubes and channels.
