AB - A model using modified superposition approach is developed to predict the  rate of heat transfer in the stagnation region of a planar jet impingement  boiling on a hot flat surface. The total heat flux in this model is based on  the combination of the single phase forced convection and nucleate pool  boiling components. The single-phase component is calculated by using  similarity solution approach. The applicability of the model is investigated  on the boiling curves under conditions of single phase, partial and fully  developed nucleate boiling. The Effect of main parameters of water jet, i.e.  jet sub-cooling, jet velocity and nozzle to plate distance on the heat flux,  is of concerned. A comparison of the obtained results of the model is made  with various published experimental data and good agreement is reported.
