摘要

The effect of stacking point location for the twist and/or taper distributions along the span of a wind turbine blade is analyzed in terms of the rotor torque. The Reynolds Averaged Navier-Stokes computations are done using the FINE/turbo flow solver developed by NUMECA International. The k-epsilon turbulence model is used to calculate the eddy viscosity. The baseline is selected as the wind turbine blade used in the National Renewable Energy Laboratory (NREL) Phase VI rotor model. The stacking point on the chordwise direction is separately defined as the sectional center for both twisting and tapering. Swept blade shapes are also analyzed using taper stacking points on the exterior of the chordline. It is observed that the generated wind power from a baseline blade may be enhanced using different stacking points without changing the twist, taper and/or airfoil profile distributions. 10-15% increase in torque values for the studied wind speeds are obtained from the investigated cases.
