Hi everybody! first of all congratulations for the forum, you have very interesting things here! This is the first time that I write a question, and I would be soooo pleased if anyone could help me. I am working with COMSOL multiphysics program, and I am trying to simulate the flux inside a microchanel that connects a microchamber and then exits through another microchanel. The problem itself is not complicated, but fluids is not my field and I am a bit lost with that... What I would like to know is which kind o flux regime I have to use (Stokes flow, laminar flow, non compresible flow, and so on...) Thanks to eerybody in advance!!!
