I am working about fluid flow over flat plate Re: 10E5.
The longitudinal velocity exceeds the inlet velocityFebruary 11, 2021 at 11:03 amFebruary 11, 2021 at 12:47 pmKarthik RAdministratorHi,nCouple of things:nA flat plate Re number of 1E6 (or 10E5) is somewhat high for a laminar flow. The flow tends to transition at around a critical Re of 5E5. If you wish to keep the flow Laminar, reduce the Re number below 5E4 (at least) to be safe. In your case, the flow might be transitioning to Turbulence and therefore is showing a different profile than the Blasius.nHave a look at the following example. I would like to particularly draw your attention to the mesh. You will need a mesh like this one to validate your model.nI hope this helps.nKarthiknFebruary 11, 2021 at 1:21 pmFebruary 11, 2021 at 10:43 pmKarthik RAdministratorHi,nYou will need a much better resolution on your mesh, especially near the wall of the flat plate. I'd strongly urge you to have a look at the mesh file from the simulation example I shared with you. This is from our AICs. This would help you get a good understanding of what you need to do.nThanks.nKarthiknFebruary 12, 2021 at 1:57 pmANSYSCOMPSubscriberThank younI will come back to younViewing 5 reply threads
