Coupling equations in OpenFoam

charlyy · July 15, 2019, 09:02

Hi all, Please I have a problem here. I am a new user of openFoam and I am doing a 1D Numerical simulation in a porous media and I have these equations to couple both the Mass equation and the heat equation.

Where:

Cp_g, lambda, Q, R, E and K are Transport Properties.

V is a vector field.

Rho_g and T are volScalarFields to be solved.

How can I solve these two coupled equations? (Tutorial on this into OpenFoam or a solver).

Thank you.

If you have some fixed velocity then you can simple go ahead with laplacian foam by adding transient term to it, followed by your second equation.

Afterwards you can solve them in segregated manner to get your results.
