Micro Wind Turbine

Hi!

I want to design and 3d print a micro wind turbine (preferably HAWT) that can spin as fast as possible in a wind speed of 4 m/s. How would I setup this simulation, and do you have any suggestions on what airfoil profile I should use for the turbine?

Thanks,

Evan

Sorry, I forgot to note this but the blades will be a length of 10 cm.

Hi Evan,

the simulation is setup in the same way as for a larger turbine.

Regarding the airfoils: for such a small turbine the Reynolds number will be very low, approximately in the range of Re ~ 1e5.

At this low Reynolds number, the influence of airfoil shape becomes less pronounced, and the aerodynamic behavior tends to resemble that of a flat plate.

BR,

David
