Note the Weibull distribution is defined only for positive value of wind speed. The other properties of the Weibull for different value of k are:1 k = 1, the Weibull distribution becomes an exponential distribution. k = 2, the Weibull distribution becomes a Rayleigh distribution (Fig. 3-4). k > 3, the Weibull distribution approaches a Gaussian distribution. 5 400 k=3 200 0 0 5 10 15 20 25 Wind speed, m/s FIGURE 3-3 The Weibull probability density function expressed in hours per year. The shaded area represents the number of hours in a year that wind speed will be between 5 and 10 m/s for the k = 1 case.

17 18 C h a p t e r Tw o r The pressure difference across the rotor creates the force that performs the work and generates power. This is counterintuitive. One would expect the wind speed to drop abruptly across the rotor. In fact, the wind speed does not drop, instead, there is an abrupt drop in pressure and the pressure energy is transferred to the rotor. Note, an abrupt drop in wind speed would cause large undesirable acceleration and force. r In the downstream volume, the static pressure rises from pr2 to p0 .
