Detailed 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 interfaceOxideRate mass model.

\[ \frac{d c}{d t} = k_{abs} w (c_{int} - c_{p_{w}}) + k_{des} (c_{p_{w}} - c_{int}) \]

\[ w = \max(1 - c_{p_{w}}/max, 0) \]

where

$ 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
Example of the boundary condition specification: 
<patchName>
{
    // Mandatory entries
    type        timeVaryingMassSorption;
    kbas        <scalar>;
    max         <scalar>;

    // Optional entries
    kdes        <scalar>;

    // Inherited entries
    ...
}

where the entries mean:

Property Description Type Reqd Deflt
type Type name: timeVaryingAdsorption word yes -
kbas Adsorption rate constant scalar yes -
max Maximum concentation at wall scalar yes -
kdes Desorption rate constant scalar no 0

The inherited entries are elaborated in:
