%X A new simple analytical model for prediction of cooling rate in the solidification process based on the local heat flux density extracted during solidification is introduced. In the modeling procedure, a solidifying control volume is considered in the mushy zone in which a heat balance equation is used to derive the present model. As the local heat flux density is a measurable parameter, the present model can be used directly on a production line. The present model was validated with numerical method and well adopted with analytical model of Garcia et al. The validation depicted that the present model can predict the cooling rate during solidification process with the same accuracy of the numerical method and Garcia’s model. Moreover, it was shown that the present model can be used to calculate the average and local cooling rate, where the available models face some difficulties.
