Detailed Description

Base class for falloff function calculators.

Each instance of a subclass of Falloff computes one falloff function. This base class implements the trivial falloff function F = 1.0.

Constructor & Destructor Documentation

Falloff ( )

inline

Default constructor is empty.

Definition at line 40 of file FalloffFactory.h.

virtual ~Falloff ( )

inlinevirtual

default destructor is empty

Definition at line 43 of file FalloffFactory.h.

Member Function Documentation

virtual void init ( const vector_fp &  c )

inlinevirtual

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.

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

Definition at line 51 of file FalloffFactory.h.

virtual void updateTemp ( doublereal  T, doublereal *  work  ) const

inlinevirtual

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 WF93, SRI5, SRI3, Troe4, and Troe3.

Definition at line 61 of file FalloffFactory.h.

virtual doublereal F ( doublereal  pr, const doublereal *  work  ) const

inlinevirtual

The falloff function.

This is defined so that the rate coefficient is

\[ k = F(Pr)\frac{Pr}{1 + Pr}. \]

Here \( Pr \) is the reduced pressure, defined by

\[ Pr = \frac{k_0 [M]}{k_\infty}. \]

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 \( F \) defined above

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

Definition at line 82 of file FalloffFactory.h.

virtual size_t workSize ( )

inlinevirtual

The size of the work array required.

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

Definition at line 87 of file FalloffFactory.h.
