IdealGasFluidProperties

These fluid properties implement the ideal gas law:

where

  • is pressure,

  • is specific volume,

  • is the universal gas constant,

  • is the temperature (in absolute units), and

  • is the molar mass.

The specific heats (isobaric, , and isochoric, ) are assumed constant, and thus their ratio is constant as well:

The specific internal energy is computed as

where is a reference specific internal energy value (corresponding to ).

The dynamic viscosity and thermal conductivity are assumed constant, though this assumption could later be dropped.
