| Zusammenfassung: | A review of wind turbine technology showed that many flaws in both the flow models and computations are involved in the traditional fundamentals. While traditional methods for design and computation are all based on the airfoil theory, a new method based on turbine theories has been developed and is shown to be ideally applicable. Against the traditional method, the new method also considers non-uniform pressure distribution in flows downstream of the rotor plane and is thus highly accurate. The blade efficiency or tip swirl number has been introduced. It enables computation of the power coefficient to be very reasonable. Its optimum can be directly applied to the geometrical design of turbine blades. Between the tip speed ratio blade efficiency and power coefficient cp, a closed solution of both the optimum design and the operation of wind turbines exists. It is demonstrated that the maximum achievable power coefficient can be 10% larger than that predicted by all previous theories. |
