Hi
I am new to OpenFoam and I just managed to run the planeWall2D tutorial (I am not quit sure about all the files). To study: Fluid mass diffusion (ie air or oxygen) through membrane (ie food bag). Next I will have platelets in it (rectangular leaving polymer space about its dimensions around it). Fick's first law is applicable, the diffusive mass flux or the analogue Fourier’s Law of Heat Conduction Heat flux (W/m2) Q1) Is there a solver for mass flux? Q2) What is the appropriate solver (laplasianfoam is only for the second law?) Q3) To start could I use files from the planeWall2D tutorial (leaving out the boundaries near the wall ? Q3.1)Is there a simpler tutorial similar to my case? Q4) In the planeWall2D tutorial if I manage to change the 1)dimensions for mass-diffusivity and concentration 2)The value of high and low concentration 3) the mass-diffusivity, would that be enough for a start? Q5) Would be easier for me to keep only the necessary files (I was not able to pick the necessary one) and build on them next? Thanks in advance |

Hi zania,
"planeWall2D"? That's not one of the official tutorials... is it this one: http://openfoamwiki.net/index.php/Ge..._-_planeWall2D If I understand your questions correctly, I think I'm only able to answer some of your questions:

Hello Bruno
Thank you for your response. That is the tutorial. I’ll check your subjections Best regards . |
