With this can you extract some information on the power generated by the turbine? or at least obtain the rotation speed? This way I could obtain the power from the velocity/power curve
At 16:18 when defining dynamic mesh zones, how do we know which ones have to be what? I understand that if we select the whole domain then we dont need to add the interior faces but we do need to add the exterior. Also the stationary is for the interface exterior interior, which we didnt create as named selections. So what is that zone?
It is simple math. Basically the function works the following way: You wan´t the velocity of the wind to be 8 m/s, but to have a smooth ramping, you can just use tis function. The velocity starts at 0 and with increasing time, the velocity reaches the desired 8 m/s. You can write that on paper and place random values for the time variable. You can see, that at 0 seconds the velocity is 0 and at some high value, like 30 seconds, the value is 8 m/s.

Great video and great music! Did some one could tell what's the music???
Hi firstly a great video.I have a problem for me ,the turbine is not rotating so what should I do. Please can you help me.
In 18:25, when the time step size is defined, you have to change it to 0.01[s]. I forgot to show that in the video.

great video!!!!!!
Hi, thanks for your tutorial. Could you share this model? Hope
Amazing!!! Thank you
for design can we just design in ansys? or first we must design at solidworks?
Can you provide ita UDF? I am new learner of cfd
Why do you checked and then unchecked the option of "coupled wall" from 14:35?
I'll admit I'm not quite sure why that is important to do, but I've checked that if you skip that step the fluid on the interior zone won't move.
@@fluentsetup1232 Interesting.

Have you got clarification about this?
How can I get power of turbine?
Can you please explain the expression you put at 14:12
have you figured it out sir?

Could u pls share the model pls
Hi, can I know how do you determine the turbine rpm from here?
Please reply if you got the answer.
Define maximum veleocity im turbine walls, then delete the maximum velocity to turbine radius. Then multiply this to 60 then you will get rpm.
how did you import from cad software to ansys? i tried but it wont work

save your cad file by clicking save as STEP214 format. open design modeller in ansys and find the STEP214 file and click generate
