Nowadays, I have been modelling a 3-D cooling plate including rectangular water channels (height=1 mm, width=0.5 mm) for Li-ion battery via Ansys Fluent. Also, there are the different type of geometric design (protrusions, dimples etc.) throughout the channels in order to enhance thermal-hydraulic performance and ensure uniform temperature distribution on battery. Although it was tried lots of mesh methods and solved the flow, it wasn't solved the numerical problems when implied the heat flux on the plate (generally "temperature limited to 1.0000e+00001 in cells.." ). I would like to grateful if you could share your recommendations and experiences about on numerical design tips of narrow channels.
Don't quite understand what you mean by "generally "temperature limited to 1.0000e+00001 in cells..""?
Dear Sir, during the my solution, I am taking this warning and the energy solution is behaving unstable effect and then my solution is divercing.
It could be anything: mesh, bc, highly nonlinear, unreasonable figure in your fluid properties, etc. You can start by assuming making silly mistake. Make sure every number is set correctly. The BCs is correct. The problem is set correctly. Then next, you can suspect your mesh is no good. If everything set correctly, mesh issue is usually the guilty party.
boyutlar çok küçük. aynı geometriyi aynı mesh ile sadece 10 kat büyük ölçekli dene büyük ihtimal aynı hatayı göstermeyecek. Göstermezse hata mesh te değil demektir.
