Abstract

A generalized analytical treatment of dimensionless equations describing turbulent forced convection and saturated nucleate boiling heat transfer leads to a new flow boiling relationship. This relationship yields a two-phase Nusselt number in terms of dimensionless parameters of the system and includes the effects of voidage and the suppression of boiling caused by the flow. It is applicable to geometries such as flow over tube bundles and flat plates in addition to the more commonly studies case of flow in tubes. The relationship is shown to correlate well the existing data on water over a wide range of conditions. A single experimentally determined factor is required and this factor is found for water and tentatively for Refrigerant 113 and cyclohexane. © 1979.
