Description🔗
The timeVaryingMassSorption
is a boundary condition that provides
a first order fixed-value condition for a given scalar field to model
time-dependent adsorption-desoprtion processes to be used with the
interfaceOxideRate
mass model
where:
Property | Description |
---|---|
\(c_{int}\) | Concentration at cell |
\(c_{p_{w}}\) | Concentration at wall |
\(k_{abs}\) | Adsorption rate constant [1/s] |
\(k_{des}\) | Desorption rate constant [1/s] |
\(w\) | Weight function |
\(max\) | Max concentration at wall |
Usage🔗
The condition requires entries in both the boundary and field files.
