Model for a Freezing Food Slab
Model for a Freezing Food Slab
Out[]=
This Demonstration shows a numerical solution for a nonlinear moving boundary model of a freezing food slab. We display the freezing or moving front (FF or MB), the convective surface temperature, the surface heat flux and the slab temperature profile (quantities labeled by PSS, for pseudo steady state). These results are compared graphically to the values obtained using the model based on Plank's equation, which assumes constant thermal properties. Due to the thermal properties (such as the thermal conductivity parameter and the dimensionless latent heat number ) on the output process quantities, the interesting effects to note are the nonlinear versus linear perturbations compared to the dominating nonlinear and effects in the above cases.
