According to the results of the tests, temperature-dependent specific heat capacities
in all shells had a similar trend, but the average and maximum values mainly depended on the phase of the starting materials and the reactions and transformations during the thermal processing, which were not readily predictable (Fig.
Also, it should be noted that uncertainties in the specific heat capacities
within the Wissler model do not affect the steady-state average skin temperature prediction.
Besides providing basic analysis and instrument control, the new software can perform a host of other functions, including partial area measurement, purity determination, kinetic analysis, specific heat capacities
and temperature programming.
The specific heat capacities
, thermal conductivity of the shell and insulating material, and the external heat transfer coefficient (HTC3) were the main parameters that influenced the temperature curves of the casting and shell.

They also concluded that the specific heat capacities
of the four preheated coatings studied differed no more than 10% below 1472F (800C), and that thermal conductivity was found to decrease as the temperature increased from 212-1292F (100-700C).
