Abstract

The jet impingement cooling technique is used for rapid surface quenching that takes place after a certain surface temperature called as the rewetting temperature. In this manuscript a theoretical model to determine the surface rewetting temperature is proposed. The rewetting temperature obtained with this model is compared with the experimental results for hot horizontal flat surface quenching. The proposed model accurately predicts the surface rewetting temperature for the stagnation point. However, for the spatial location up to 12 mm. the rewetting temperature falls within the error band of ± 15 percent. This variation for the downstream locations is due to retardation of jet flow over hot surface. Since, jet velocity has been considered as one of the depending variables in determining the heat transfer, however, its retarding effect for the downstream location has not been incorporated in the model.
