The governing equations of the problem in enthalpy form are nondimensioned as equations set (1) using following nondimensional distance, time, temperature, enthalpy, Stefan number and boundary heat flux
A quantitative representation of the effect of Stefan number, the RMS error for a wide range of Stefan number at different sensor locations is presented in Table 1 for step heat flux.
Table 1 Comparison of RMS of computed heat flux for different Stefan numbers RMS Error (%) Stefan Number [X.
The Stefan number is the ratio of the latent heat to the product of the specific heat and imposed temperature difference.
The Stefan number St, which is the ratio of heat released during crystallization and the heat capacity of the body, is a constant for all four cases discussed above.
