Detailed Description

Class describing one isotherm with possibly precalculated interpolation table.

Definition at line 158 of file isotherm.hh.

Member Enumeration Documentation

enum Isotherm::SorptionType

Type of adsorption isotherm.

Enumerator
none
linear
freundlich
langmuir

Definition at line 174 of file isotherm.hh.

Constructor & Destructor Documentation

Isotherm::Isotherm ( )

Default constructor.

Definition at line 32 of file isotherm.cc.

Member Function Documentation

void Isotherm::clear_table ( )

Clears the interpolation table and resets the table limit. (That means, no interpolation takes place in the computation.)

Definition at line 37 of file isotherm.cc.

Here is the caller graph for this function:

void Isotherm::compute	(	double &	c_aqua,
		double &	c_sorbed
	)

Direct calculation of the equilibrium adsorption using a non-linear solver. reinit has to be called just before this method.

Definition at line 68 of file isotherm.cc.

Here is the caller graph for this function:

Isotherm::ConcPair Isotherm::compute_projection ( Isotherm::ConcPair c_pair )

protected

Update concentrations using interopolation.

Definition at line 100 of file isotherm.cc.

Here is the caller graph for this function:

Isotherm::DECLARE_EXCEPTION	(	ExcBoostSolver	,
		<< "The Boost solver of nonlinear equation did not converge in sorption model.\n"<< "Check input at the following address for possible user error: \t"<< Input::EI_Address::val<< "\n""Solver message: \n"<< EI_BoostMessage::val
	)

Isotherm::DECLARE_EXCEPTION	(	ExcNegativeTotalMass	,
		<< "The total mass in sorption model became negative during the computation (value: "<< EI_TotalMass::val<< ").\n"<< "Check input at the following address for possible user error: \t"<< Input::EI_Address::val<< "\n"
	)

double Isotherm::get_total_mass ( ConcPair conc )

protected

Definition at line 62 of file isotherm.cc.

Here is the caller graph for this function:

void Isotherm::interpolate	(	double &	c_aqua,
		double &	c_sorbed
	)

Use interpolation to determine equilibrium state. Assumes previous call to make_table. If total mass is larger then table limit we either call precipitate (limit_solubility_on) or use direct computation.

Definition at line 84 of file isotherm.cc.

Here is the caller graph for this function:

bool Isotherm::is_precomputed ( void )

inline

Returns true if interpolation table is created.

Definition at line 239 of file isotherm.hh.

Here is the caller graph for this function:

void Isotherm::make_table	(	unsigned int	n_points,
		double	table_limit
	)

Create interpolation table for isotherm in rotated coordinate system with X axes given by total mass in both phases. Currently we support only linear interpolation. reinit has to be called just before this method.

Parameters

n_points	is the size of the table
table_limit	is the limit value of aqueous concentration

Definition at line 259 of file isotherm.cc.

void Isotherm::make_table	(	const None &	isotherm,

template<class Func >

void Isotherm::make_table	(	const Func &	isotherm,
		int	n_points
	)

protected

Implementation of interpolation construction for particular isotherm functor. Specialized for sorption 'none' - creates empty table.

Definition at line 217 of file isotherm.cc.

Isotherm::ConcPair Isotherm::precipitate ( Isotherm::ConcPair c_pair )

protected

Modify concentrations after adsorption for limited solubility.

Definition at line 127 of file isotherm.cc.

Here is the caller graph for this function:

void Isotherm::reinit	(	enum SorptionType	sorption_type,
		bool	limited_solubility_on,
		double	aqua_density,
		double	scale_aqua,
		double	scale_sorbed,
		double	c_aqua_limit,
		double	mult_coef,
		double	second_coef
	)

Setting adsorption parameters for general isotherm. These parameters are then used either for creation of the interpolation table via make_table method or just one adsorption is computed through compute method. Provided parameters are:

Parameters

sorption_type	- type of isotherm
limited_solubility_on	- true if `c_aqua_limit` is solubility limit
aqua_density	- density of the liquid phase
scale_aqua	- generalized porosity, fraction of the space with liquid phase
scale_sorbed	- fraction of the space with the solid to which we adsorp
c_aqua_limit	- solubility limit (limit aqueous concentration)
mult_coef	- multiplicative coefficient of the isotherm (all isotherms have one)
second_coef	- possibly second parameter of the isotherm

Definition at line 44 of file isotherm.cc.

Find new values for concentrations in c_pair that has same total mass and lies on the isotherm (functor object). Specialized for sorption 'none' - returns unchanged c_pair.
