 October 28, 2009, 02:29 Boundary Condition for ducted wind turbine using FLUENT #1 New Member   Boris Styward Join Date: Oct 2009 Posts: 6 Rep Power: 8 i have a problem with my thesis using FLUENT, the problem is i have to simulate a wind turbin in duct, the main problem what is the right boundary condition for this situation? can i use pressure inlet for the inlet, and pressure outlet for the outlet, or mass flow inlet for the inlet and pressure outlet for the outlet. What is the advantages and disadvantages if i use that combination or the other combinations? i'm sorry, i've made a same thread, but in a wrong sub-forum, maybe this is the right room Thank you FYI

Your Forum will be: -> ANSYS -> FLUENT Concerning your problem: You can use both combinations you named. It depends on your knowlege about measurements and the real conditions. You can do any combination of boundary conditions except for: velocity - mass flow velocity - velocity mass flow - mass flow (they are violating continuity equation [incompressible flows])
