hello all,
I made some progress in my work about my Wind tunnel but now I am really blocked. In the best case, I'd like to have three speed condition in my mesh with a "double-inlet" as shown in the figure enclosed. The side conditions are the same on the four sides of the air bloc, a Wind speed with angle. On the face of the bloc we just add some velocity for the flow to stay the same at the inlet and the outlet as we work with incompressible. Because we know the flow within the Wind tunnel and we know that the Wind outside will take some value of velocity and angle but nothing else. But I read that if you make 2 speed boundary conditions your system won't be stable. And, after testing, I agree. Please tell me if system like this can be Meshed and what should I do in my case! Why it is not working? How can we modelize open Wind tunnel? thank you for your time Elisa Last edited by Elisa-L; June 1, 2015 at 02:02. Reason: mistake |
