Detailed Description

The NASA 9 polynomial parameterization for a single species encompassing multiple temperature regions.

The parameterization used in each temperature range is described in the documentation for class Nasa9Poly1.

These NASA representations may have multiple temperature regions through the use of this Nasa9PolyMultiTempRegion object, which uses multiple copies of the Nasa9Poly1 object to handle multiple temperature regions.

Constructor & Destructor Documentation

◆ Nasa9PolyMultiTempRegion()

Nasa9PolyMultiTempRegion ( std::vector< Nasa9Poly1 *> & regionPts )

Constructor used in templated instantiations.

Parameters

regionPts Vector of pointers to Nasa9Poly1 objects. These objects all refer to the temperature regions for the same species. The vector must be in increasing temperature region format. Together they represent the reference temperature parameterization for a single species.

Note, after the constructor, we will own the underlying Nasa9Poly1 objects and be responsible for owning them.

Member Function Documentation

◆ reportType()

int reportType ( ) const

virtual

Returns an integer representing the type of parameterization.

Implements SpeciesThermoInterpType.

References NASA9MULTITEMP.

◆ temperaturePolySize()

virtual size_t temperaturePolySize ( ) const

inlinevirtual

Number of terms in the temperature polynomial for this parameterization.

Reimplemented from SpeciesThermoInterpType.

Definition at line 56 of file Nasa9PolyMultiTempRegion.h.

◆ updateTemperaturePoly()

void updateTemperaturePoly	(	double	T,
		double *	T_poly
	)		const

virtual

Given the temperature T, compute the terms of the temperature polynomial T_poly.

Reimplemented from SpeciesThermoInterpType.

Definition at line 64 of file Nasa9PolyMultiTempRegion.cpp.

◆ updateProperties()

void updateProperties	(	const doublereal *	tt,
		doublereal *	cp_R,
		doublereal *	h_RT,
		doublereal *	s_R
	)		const

virtual

Update the properties for this species, given a temperature polynomial.

This method is called with a pointer to an array containing the functions of temperature needed by this parameterization, and three pointers to arrays where the computed property values should be written. This method updates only one value in each array.

The form and length of the Temperature Polynomial may vary depending on the parameterization.

Parameters

tt	vector of evaluated temperature functions
cp_R	Vector of Dimensionless heat capacities. (length m_kk).
h_RT	Vector of Dimensionless enthalpies. (length m_kk).
s_R	Vector of Dimensionless entropies. (length m_kk).

Temperature Polynomial:

tt[0] = t;
tt[1] = t*t;
tt[2] = t*t*t;
tt[3] = t*t*t*t;
tt[4] = 1.0/t;
tt[5] = 1.0/(t*t);
tt[6] = std::log(t);

Reimplemented from SpeciesThermoInterpType.

◆ updatePropertiesTemp()

void updatePropertiesTemp	(	const doublereal	temp,
		doublereal *	cp_R,
		doublereal *	h_RT,
		doublereal *	s_R
	)		const

virtual

Compute the reference-state property of one species.

Given temperature T in K, this method updates the values of the non- dimensional heat capacity at constant pressure, enthalpy, and entropy, at the reference pressure, of the species.

Parameters

temp	Temperature (Kelvin)
cp_R	Vector of Dimensionless heat capacities. (length m_kk).
h_RT	Vector of Dimensionless enthalpies. (length m_kk).
s_R	Vector of Dimensionless entropies. (length m_kk).

Implements SpeciesThermoInterpType.
