Full TextAbstract
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.
