Abstract

As we have explained extensively in the previous chapters the blade-element-momentum method describes blades—aerodynamically—as a set of independent 2D airfoils. Therefore, wind tunnel measurement of 2D sections is the basis of all aerodynamical experiments for wind turbines. Fortunately, a lot of experience has been gained for airfoils of airplanes which could be used when special airfoils started to be designed [33] in Chap. 9.

Vorheriges Kapitel Application of Computational Fluid Mechanics

Nächstes Kapitel Impact of Aerodynamics on Blade Design

This code is comparable to the so-called Eppler-code [17] in Chap. 3, developed somewhat earlier and was extended to include 3D-effect from stall-delay for rotation in [32].

Roughly speaking this is the ratio where a small disturbance has grown to a relevant size.

In [15, 16] even a much lager range of \(\nu < 500\) Hz is excluded.
