Accurate simulation of the freezing process and prediction of freezing time are important for the design and control of freezing devices and assurance of product quality. Based on the prediction model of thermophysical parameters and an enthalpy-based mathematical model for silver carp muscle, a finite difference method was adopted to establish a physical model for flat silver carp muscle. The freezing process and freezing time for the thermal center and boundary layer of the silver carp muscle were also pr...
