Constructor & Destructor Documentation

◆ SootSpectrumProperties()

ablate::eos::radiationProperties::SootSpectrumProperties::SootSpectrumProperties	(	std::shared_ptr< eos::EOS >	eosIn,
		int	num = `0`,
		double	min = `0.4E-6`,
		double	max = `30E-6`,
		const std::vector< double > &	wavelengths = `{}`,
		const std::vector< double > &	bandwidths = `{}`
	)

If a range is given, initialize a linear variation in wavelength over the desired range.

Default the bandwidths to cover the whole range.

◆ GetRadiationPropertiesTemperatureFunction()

ablate::eos::ThermodynamicTemperatureFunction ablate::eos::radiationProperties::SootSpectrumProperties::GetRadiationPropertiesTemperatureFunction	(	RadiationProperty	property,
		const std::vector< domain::Field > &	fields
	)		const

virtual

Function to produce radiation absorption properties based upon the available fields and temperature

Parameters

property
fields

Returns

Check if the species exist in this run. If all don't exist, throw an error. If some don't exist, then the values should be set to zero for their mass fractions in all cases.

Get the offsets that locate the position of the solid carbon field.

< Create a struct to hold the offsets

Implements ablate::eos::radiationProperties::RadiationModel.

◆ SootAbsorptionTemperatureFunction()

PetscErrorCode ablate::eos::radiationProperties::SootSpectrumProperties::SootAbsorptionTemperatureFunction	(	const PetscReal *	conserved,
		PetscReal	temperature,
		PetscReal *	kappa,
		void *	ctx
	)

static

This model depends on mass fraction, temperature, and density in order to predict the absorption properties of the medium.

< Variables to hold information gathered from the fields Standard PETSc error code returned by PETSc functions

< Get the density value at this location

< Get the mass fraction of carbon here

Must convert to micrometers because of the model fit

This is the wavelength. (We must integrate over the valid range of wavelengths.)

Fit of model to data.

◆ SootEmissionTemperatureFunction()

PetscErrorCode ablate::eos::radiationProperties::SootSpectrumProperties::SootEmissionTemperatureFunction	(	const PetscReal *	conserved,
		PetscReal	temperature,
		PetscReal *	epsilon,
		void *	ctx
	)

static

Get the black body intensity at the temperature and wavelength specified.

Multiply it by the bandwidth under constant assumption to get the power integration.

In other models we may want to implement a smarter integration.
