Computational observations of the tip loss mechanism experienced by horizontal axis rotors

Abstract:

Blade resolved computations of two different horizontal axis rotors are conducted to investigate the tip loss mechanism experienced by horizontal axis rotors. The tip loss mechanism specifically refers to the effect of the vorticity that is shed from the outboard blade sections, which results in the blade loading dropping off as the tip is approached. In this paper, the shed vorticity is shown to induce a downwash at the rotor plane and spanwise flow accelerations along the blade surfaces. Wh...
