Detailed Description

An abstract base class for evaluating all reactions of a particular type.

Because this class has no template parameters, the Kinetics object can store all of these rate coefficient evaluators as a vector<shared_ptr<MultiRateBase>>. All of the actual implementation for this capability is done in the MultiRate class.

Member Function Documentation

◆ type()

virtual string type ( )

pure virtual

Identifier of reaction rate type.

Implemented in MultiRate< RateType, DataType >.

◆ add()

virtual void add	(	size_t	rxn_index,
		ReactionRate &	rate
	)

pure virtual

Add reaction rate object to the evaluator.

Parameters

rxn_index	index of reaction
rate	reaction rate object

Implemented in MultiRate< RateType, DataType >.

virtual bool replace	(	size_t	rxn_index,
		ReactionRate &	rate
	)

pure virtual

Replace reaction rate object handled by the evaluator.

Parameters

rxn_index	index of reaction
rate	reaction rate object

Implemented in MultiRate< RateType, DataType >.

◆ resize()

virtual void resize ( Kinetics & kin )

pure virtual

Update array sizes that depend on number of species, reactions or phases.

Since: Changed in Cantera 4.0 to take a Kinetics object as argument instead of specific array sizes.

Implemented in MultiRate< RateType, DataType >.

◆ getRateConstants()

virtual void getRateConstants ( span< double > kf )

pure virtual

Evaluate all rate constants handled by the evaluator.

Parameters

kf	array of rate constants

Implemented in MultiRate< RateType, DataType >.

◆ modifyRateConstants()

virtual void modifyRateConstants	(	span< double >	kf,
		span< double >	kr
	)

pure virtual

For certain reaction types that do not follow mass action kinetics (for example, Butler-Volmer), calculate modifications to the forward and reverse rate constants.

Parameters

[in,out]	kf	On input, contains the rate constants as computed by getRateConstants(). The output value is updated by the reactant StoichManagerN to determine the forward rates of progress.
[in,out]	kr	On input, contains the reverse rate constants computed from the forward rate constants and the equilibrium constants. The output value is updated by the product StoichManagerN to determine the reverse rates of progress.

Since: New in Cantera 3.2

Implemented in MultiRate< RateType, DataType >.

◆ processRateConstants_ddT()

virtual void processRateConstants_ddT	(	span< double >	rop,
		span< const double >	kf,
		double	deltaT

pure virtual

Evaluate all rate constant temperature derivatives handled by the evaluator; which are multiplied with the array of rate-of-progress variables.

Depending on the implementation of a rate object, either an exact derivative or a numerical approximation may be used.

Parameters

[in,out]	rop	array of rop, which is modified by the method; contains rop on input, and d(rop)/dT on output
	kf	array of forward rate constants (numerical derivative only)

	kf	array of forward rate constants
	deltaP	relative pressure perturbation

Implemented in MultiRate< RateType, DataType >.

Returns: flag indicating whether reaction rates need to be re-evaluated

Implemented in MultiRate< RateType, DataType >.

◆ evalSingle()
