Detailed Description

Arrhenius reaction rate type depends only on temperature.

A reaction rate coefficient of the following form.

\[ k_f = A T^b \exp (-E/RT) \]

Definition at line 31 of file RxnRates.h.

Constructor & Destructor Documentation

Arrhenius ( )

Default constructor.

Definition at line 8 of file RxnRates.cpp.

Arrhenius ( const ReactionData & rdata )

explicit

Constructor from ReactionData.

Definition at line 16 of file RxnRates.cpp.

Arrhenius	(	doublereal	A,
		doublereal	b,
		doublereal	E
	)

Constructor.

Parameters

A	pre-exponential. The unit system is (kmol, m, s). The actual units depend on the reaction order and the dimensionality (surface or bulk).
b	Temperature exponent. Non-dimensional.
E	Activation energy in temperature units. Kelvin.

Member Function Documentation

static int type ( )

inlinestatic

return the rate coefficient type.

Definition at line 35 of file RxnRates.h.

void update_C ( const doublereal * c )

inline

Update concentration-dependent parts of the rate coefficient.

For this class, there are no concentration-dependent parts, so this method does nothing.

Definition at line 58 of file RxnRates.h.

doublereal update	(	doublereal	logT,
		doublereal	recipT
	)		const

inline

Update the value of the logarithm of the rate constant.

Note, this function should never be called for negative A values. If it does then it will produce a negative overflow result, and a zero net forwards reaction rate, instead of a negative reaction rate constant that is the expected result.

Deprecated:: . To be removed after Cantera 2.2

Definition at line 70 of file RxnRates.h.

doublereal updateLog	(	doublereal	logT,
		doublereal	recipT
	)		const

inline

Update the value of the natural logarithm of the rate constant.

Definition at line 77 of file RxnRates.h.

doublereal updateRC	(	doublereal	logT,
		doublereal	recipT
	)		const

inline

Update the value the rate constant.

This function returns the actual value of the rate constant. It can be safely called for negative values of the pre-exponential factor.

Definition at line 88 of file RxnRates.h.

void writeUpdateRHS ( std::ostream & s ) const

inline

Deprecated:: . To be removed after Cantera 2.2

Definition at line 93 of file RxnRates.h.

double preExponentialFactor ( ) const

inline

Return the pre-exponential factor A (in m, kmol, s to powers depending on the reaction order)

Definition at line 106 of file RxnRates.h.

double temperatureExponent ( ) const

inline

Return the temperature exponent b

the activation temperature) [K]
