The tip speed ratio λ

Webλ = R Ω / V = 2 π N R / V. where Ω is the angular velocity and N is the rotational speed of the rotor. The power coefficient and torque coefficient of a rotor vary with the tip speed ratio. … WebFor this study the well-known ADM-airfoil and the ALM-airfoil are chosen. The inflow velocity is fixed at U hub =8 m s −1 and the tip speed ratio at λ=7.55 in order to compare the results with the ones published by Asmuth et al. . At this velocity, the rotational speed is approximately Ω=9.15 rpm = 0.95 s −1.
