Internals

These are utility / unexported functions for those wanting to learn or extend SorptionModels.

Many model methods are implemented that are used for various downstream analyses.

SorptionModels.nparams — Function

Get the number of adjustable parameters in the model. This will not include non-adjustable (but required) arguments that some models may have.

SorptionModels.thermodynamic_factor — Function

Calculate the thermodynamic factor (see ThermodynamicFactorAnalysis) of a component in a polymer for a pure sorption model.

thermodynamic_factor(models::AbstractVector{<:SorptionModel}, pressures::AbstractVector{<:Number}, ρpol_g_cm3::Number, pen_mws::AbstractVector{<:Number}, zs::AbstractVector{<:Number}=ones(length(models))

(EXPERIMENTAL) Calculate the thermodynamic factor (see ThermodynamicFactorAnalysis) of a component in a polymer for a mixed sorption model. This works by providing a vector of pure models, and implicitly uses their mixing rules to get back thermodynamic factors. Indices should represent components.

source

SorptionModels.dc_dp — Function

dc_dp(model::SorptionModel, p_mpa::Number)

Calculate the derivative of concentration (cc/cc) with respect to pressure (MPa).

source

SorptionModels.dp_dc — Function

dp_dc(model::SorptionModel, p_mpa::Number)

Calculate the derivative of pressure (MPa) with respect to concentration (cc/cc).
