You're reading the documentation for a development version. For the latest released version, please have a look at v4.4.0.
Parameter Dependencies¶
Some parameters depend on other parameters (parameter-parameter dependency) or the solution variables (parameter-state dependency). Parameter dependencies are defined in the unit operation scope.
Parameter-Parameter Dependencies¶
Group /input/model/unit_XXX¶
COL_DISPERSION_DEP
Parameter dependence of column dispersion on the interstitial velocity. Available for the LRM, LRMP and GRM units (with FV discretization only at the moment)
Type: string
Range: \(\texttt{POWER_LAW}\)
Length: 1
FILM_DIFFUSION_DEP
Parameter dependence of film diffusion on the interstitial velocity. Available for the LRMP unit (with FV discretization only at the moment)
Type: string
Range: \(\texttt{POWER_LAW}\)
Length: 1
Correlations¶
Different types of parameter correlations are can be applied.
The following correlations can be used for all parameter-parameter dependencies, but we specify the required input fields only for COL_DISPERSION_DEP, for the sake of conciseness.
Power Law
Here, \(p_{dep}\) is the dependent parameter and \(p_{on}\) is the parameter it depends on.
COL_DISPERSION_DEP_BASE
Base \(b\) of the power law parameter dependence. Optional, defaults to \(1.0\)
Type: double
Range: \(\mathbb{R}\)
Length: 1
COL_DISPERSION_DEP_EXPONENT
Exponent \(x\) of the power law parameter dependence
Type: double
Range: \(\mathbb{R}\)
Length: 1
COL_DISPERSION_DEP_ABS
Specifies whether or not the absolute value should be computed. Optional, defaults to \(1\)
Type: int
Range: \(\{0, 1\}\)
Length: 1
Parameter-State Dependencies¶
Group /input/model/unit_XXX¶
Parameter-State Dependencies are not fully implemented yet.
