Rewetting model using a generalized boiling curve. [PWR, BWR]
An analytical one-dimensional conduction model is developed for the rewetting of a hot surface. A generalized boiling curve is applied to account for the various heat transfer regimes involved in the quenching phenomenon. A non-dimensional velocity is defined, which plays the role of an eigenvalue in the solution of the governing equation and is shown to generalize the applicability of the predicted results for a wide range of experimental conditions. The method is applicable for an arbitrary distribution of heat flux in the sputtering region and does not require the conventional a-priori definition of a rewetting temperature.
