Virtual Wind Tunnel in FLUENT
Hi everyone, I am trying to simultae a fan driven wind tunnal in a room through Fluent. Problem is that when I run the simulation, I can see the velocity/pressure etc variations within the wind tunnel but there is almost no effect around the inlet and outlet of the wind tunnel...Any Idea? I have tried Pressure inlet, Mass flow inlet , pressure outlet, outflow etc in different combinations for inlet and outlet conditions. Fan is inside the wind tunnel (a face). I have two seperate interior fluid domains of room (excluding wind tunnel) and wind tunnel itself. Tne inlet and outlet of wind tunnel is with a common face to outer domain (room) and inner domain (windtunnel). Thanks in anticipation...
