IdealGasFluidPropertiesPT

Fluid properties for an ideal gas

A simple formulation that is suitable for ideal gases, where properties are derived from the ideal gas law (1)

Internal energy of an ideal gas is (2)

while enthalpy is (3)

All other properties (such as viscosity or thermal conductivity) are assumed to be constant in this fluid, and must be provided in the input file (see below).
