concLaminarTurbulentFoam

Script based on scalarTransportFoam in order to predict, with the help of Navier-Stokes Eqs., laminar and turbulent mass-transfer behaviour in electrochemical reactors.

Usage

In solvers (A) you will find the scripts to compile the solvers in order to solve the concentration field either in laminar or turbulent conditions knowing the velocity profile.
For OpenFOAM 6 and later. Both solvers are in one. For the laminar situation do not supply nut or nut = zero. In tutorial (B) you will find an example for a parallel plates reactor with high aspect ratio (elecrode width/interelectrode gap).

# A) Compile Solvers

1- Paste concentrationFoam (and/or turbulentConcentrationFoam for OpenFOAM 4,5) inside OpenFOAM user directory (Applications/Utilities/Solvers).
2- Enter to concentrationFoam (and/or turbulentConcentrationFoam for OpenFOAM 4,5) and open a terminal.
3- Run wmake.

# B) Run tutorial

1- Paste Navier-Stokes and concentration inside OpenFOAM user directory (Run/Tutorials).
2- Enter to Navier-Stokes and open a Terminal. 3- Modify properties inside constant folder for laminar or turbulent flow.
4- Run blockMesh and then Run simpleFoam.
5- Paste U (laminar and turbulent) and nut (turbulent) obtained as solution inside the 0 folder of concentration.
6- Open a terminal inside concentration and Run blockMesh, then Run concentrationFoam (and/or turbulentConcentrationFoam for OpenFOAM 4,5).
