Member Function Documentation

virtual doublereal F	(	doublereal	pr,
		const_workPtr	work
	)			const [pure virtual]

The falloff function.

This is defined so that the rate coefficient is

Here is the reduced pressure, defined by

Parameters:

	pr	reduced pressure (dimensionless).
	work	array of size workSize() containing cached temperature-dependent intermediate results from a prior call to updateTemp.

Returns:

Returns the value of the falloff function defined above

Implemented in Troe3, Troe4, SRI3, SRI5, and WF93.

virtual void init

(

const vector_fp &

c

)

[pure virtual]

Initialize.

Must be called before any other method is invoked.

Parameters:

c

Vector of coefficients of the parameterization. The number and meaning of these coefficients is subclass-dependent.

Implemented in Troe3, Troe4, SRI3, SRI5, and WF93.

virtual void updateTemp	(	doublereal	T,
		workPtr	work
	)			const [inline, virtual]

Update the temperature-dependent portions of the falloff function, if any.

This method evaluates temperature-dependent intermediate results and stores them in the 'work' array. If not overloaded, the default behavior is to do nothing.

Parameters:

	T	Temperature [K].
	work	storage space for intermediate results.

Reimplemented in Troe3, Troe4, SRI3, SRI5, and WF93.

Definition at line 70 of file FalloffFactory.h.

virtual size_t workSize

(

)

[pure virtual]

The size of the work array required.

Implemented in Troe3, Troe4, SRI3, SRI5, and WF93.
