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).

Optional Parameters

  • control_tagsAdds user-defined labels for accessing object parameters via control logic.

    C++ Type:std::vector

    Description:Adds user-defined labels for accessing object parameters via control logic.

  • enableTrueSet the enabled status of the MooseObject.

    Default:True

    C++ Type:bool

    Description:Set the enabled status of the MooseObject.

  • allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

    Default:False

    C++ Type:bool
