Micro Wind Turbine
Quote from Evan on 24. March 2025, 23:48Hi!
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

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.
