Detailed Description

Fluid is the abstract base class that is employed by all the other fluids.

Definition at line 147 of file FluidClass.h.

Constructor & Destructor Documentation

Fluid::Fluid ( )

inline

A vector of instances of the phi_BC classes for the ideal-gas Helmholtz energy contribution.

Constructor for the Fluid class. This is an abstract base class that is not meant to be instantiated directly. Rather it should be subclassed to implement new fluids. Examples of this behavior are the R134aClass or the R290Class classes.

Default molar gas constant [kJ/kmol/K]

true if fluid is one-component pure fluid, false otherwise

		double	rho,
		Fluid *	ReferenceFluid
	)

This function is optional, and returns a NotImplementedError if the derived class does not implement it. Hopefully the calling function catches the error

Parameters

T	Temperature [K]
rho	Density [kg/m3]
ReferenceFluid	A pointer to an instance of a Fluid class that is used as the reference fluid for the ECS model

Definition at line 3472 of file FluidClass.cpp.

virtual double Fluid::viscosity_residual	(	double	T,
		double	rho
	)

inlinevirtual

The residual viscosity for the fluid. The sum of the background and critical contributions. This function is optional, and returns a NotImplementedError if the derived class does not implement it. Hopefully the calling function catches the error

See also: viscosity_Trho

Parameters

T	Temperature [K]
rho	Density [kg/m3]

Reimplemented in EthaneClass, R134aClass, R290Class, MethaneClass, and NitrogenClass.
