Hello,
i will simulate a diffuser with an energy dissipating screen. In windtunnel experiments, the screen was realized by an screen of wires (with a pressure difference) wich dissipate the kinetic Energy to heat. In Simulation, I will represent the screen by a POROUS Domain. My questions: -Is the POROUS-Domain the accurate way (because I got no good results)? -And how can I calculate the the Porosity, Permability and the Loss-Faktor when I Know the pressure difference of the screen? (The ANSYSCFX equation 244 is not enough, because I need 2 equations for the 2 variables Pemability and Loss-Faktor) Thanks for your help! and I hope I can give it back |
