Abstract : Turbulent film condensation for liquid metals was investigated using both Nusselt's model and the two-phase model. The effect of turbulent transport was expressed by the eddy kinematic viscosities of Deissler and von Karman. The predictions of the average heat transfer coefficient are higher than the liquid metal data of Misra and Bonilla. However, under the premise that there is an upward vapor flow, it is shown qualitatively that an upward vapor flow can greatly reduce the heat transfer coefficient. The observed scatter of data may be attributable to the variations of vapor velocity. (Author)
