Description
|
||||
This boundary condition provides a first order fixed-value condition
|
||||
for a given scalar field to model time-dependent adsorption-desoprtion
|
||||
processes to be used with the \c interfaceOxideRate mass model
|
||||
|
||||
\f[
|
||||
\frac{d c}{d t} =
|
||||
k_{abs} w (c_{int} - c_{p_{w}}) + k_{des} (c_{p_{w} - c_{int}})
|
||||
\f]
|
||||
|
||||
\f[
|
||||
w = max(1 - c_{p_{w}/max, 0);
|
||||
\f]
|
||||
|
||||
where
|
||||
\vartable
|
||||
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
|

\endvartable

|

Usage
|
||||
Example of the boundary condition specification:
|
||||
\verbatim
|
||||
<patchName>
|
||||
{
|
||||
// Mandatory entries
|
||||
type timeVaryingMassSorption;
|
||||
kbas <scalar>;
|
||||
max <scalar>;
|
||||
|
||||
// Optional entries
|
||||
kdes <scalar>;
|
||||
|
||||
// Inherited entries
|
||||
...
|
||||
}
|
||||
\endverbatim
|
||||
|
||||
where the entries mean:
|
||||
\table
|
||||

|
||||
type | Type name: timeVaryingAdsorption | word | yes | -
|
||||

|
||||
max | Maximum concentation at wall | scalar | yes | -
|
||||
kdes | Desorption rate constant | scalar | no | 0
|
||||
\endtable
