Hello. Nice turorial. A short question: You are using an unstructured mesh where the faces and the direction of the main flow have a varying angle. I used an structured mesh and experienced a much narrower region where the species mix due to diffusion. Is it possible that the broader region of mixing in this simulation originates from numerical artificial diffusion due to high gradients between mesh face direction and background flow ? Thanks.
Hi, I want to simulate a biological Methanation process. In a Pipe I have 2 inlets and 1 outlet. In the first inlet should flow in water and in the second inlet should flow in a (hydrogen/carbon dioxid) mix. my goal is to obtain methane in the output by a chemical reaction. Wich Physics do i need for this Process? Murat
It's numerics, not physics. ;-) The concentration gradient is huge at that point. I would expect some numerical overshooting without further fine-tuning.
