HEAT TRANSFER CRISIS AT WATER BOILING IN ANNULAR CHANNELS WITH EXTERNAL AND INTERNAL HEATING
Abstrakt
Investigation results on regularity of heat transfer crisis occurance in annular channels and peculiarities of this phenomenon as related to large volume and tubes are presented. Influence of heating mode, heat transfer surface curvature and other determining parameters (pressure, fluid velocity, its subcooling and geometrical parameters of the annular channel) on the value of heat flux critical density qcr been studied. Design equations for determining of qcr in annular channels are proposed.
