Three types of fidelity can be used in the current version of the Heat Transfer Library. There is a trade-off between the capability of the physical phenomena expression and the simulation cost. Thus, you need to specify it with your purpose of simulation.
If you use this mode, the properties is assigned with the following constants.
Specific heat capacity at the constant pressure :
Molar mass :
Gas constant :
(*) is Universal gas constant, and the value is
Specific heat capacity at the constant volume :
Dynamic viscosity :
Thermal conductivity :
And, the specific enthalpy is calculated with the following equation, and which is called as :
(*) The offset value of specific enthalpy is defined to be the same value as the other types of property at 273.15[K] and 101325[Pa]
