Study on film boiling heat transfer for water jet impinging on high temperature flat plate

An theoretical and experimental study on film boiling heat transfer for water jet impinging on the horizontal high temperature flat plate is performed for the jet stagnation zone. Simplified two-phase flow boundary layer equations were used to calculate the thickness of the vapor layer and from it the heat transfer coefficient of film boiling is obtained. A semi-empirical correlation is proposed for predicting the heat transfer coefficient of film boiling.
