MaterialPropertyLib::VapourDiffusionDeVries Class Referencefinal

Detailed Description

DeVries type Vapour diffusion.

The model was presented in [12].

The vapour diffusion can be described by

\[ D_v=5.9\cdot 10^{-6} \frac{\left(T\, \text{in K}\right)^{2.3}}{p, \text{in Pa}} D_{vr}, \]

where \(D_{vr}\) is the the relative diffusion coefficient, and \(T\) is the temperature.

This virtual method will compute the property derivative value based on the variables that are passed as arguments with the default implementation using empty variables array for the previous time step.

The default implementation of this method only returns the property value derivative without altering it.
