Hello everyone,
I am trying to simulate T-shaped micromixer from a previously published paper, I think I used the correct physics models (Laminar flow and transport diluted species). In the paper, obstacles simulated inside the microchannel, I have a question regarding what boundary condition should I use for the obstacles walls. I tried (open boundary) but I did not get the nice mixing similar to the paper.
Any help would truly be appreciated! Paper: http://tpnms.usb.ac.ir/article_2034_da536b7d34c59c483fcc918b9404b52e.pdf
