Wind Turbine with SRF

tomson199 · September 30, 2015, 05:19

Hi,

I'm trying to simulate a wind turbine using single rotating reference frame model (SRF). I made one domain, which it rotates with rotational velocity of blade. Steady-state simulation looks good, but when I simulate this in transient, I've cannot see the revolution of blade with respect of time. Changing the time step in timestep selector in CFD Post cause not effect in rotate of my rotor. Do you have any idea how to solve this issue?

Have you checked your ANSYS CFD-Post options ?

Look for "Do not rotate, Always Rotate, Automatic". For single domain without frame change, you may need to use "Always Rotate"

I tried to find this option but I don't know where I can find this button to solve my issue. Could you tell me how to turn on this option to see how my rotor rotate ?

Ok I got it. Thanks!

Can you please tell me how to initialize the cell zone condition and wall condition for the srf simulation..Pictures of the process would be appriciated.
