Torque Calculation
 

Hi,

I am simulating an axial flow air turbine (the Wells turbine for extracting wave energy) using MRF. The problem is when i calculate the blade torque, it gives a value close to zero!


The solution is converged well but the problem is with the moment report. my torque is very low . I tried different mesh topologies and all give me almost the same number (which is very low compared to experiments). Is there any adjustment that must be made in fluent before starting the calculations?



I am really grateful that guide me about this.

Thanks,

Best,

Aja

Can anybody assist?

Thanks

The value of torque depends on the blade pitch angle or twist. If your blade is straight, no twist, no pitch angle or no flow angle of attack then torque will be minimum.

Try giving flow velocity components to set flow angle of attack.

Share geometric specifications, if possible.

Hope it will help.
