摘要
本文根据修正的动量理论和叶素理论,导出了用气流角(?)表示的风轮最大功率系数C_(Pmax)的解析表达式.由于C_(Pmax)及速度诱导系数等均以显式给出,使气动特性优化设计过程极为简单,避免了一般设计方法中所需的迭代过程,程序简单,计算省时,结果准确可靠.
In the present paper, based on the modified momentum theory
and blade-element theory, an analytic formula of the maximun power coefficient Cpmax of a rotor is derived. Because the CPmax and all the other aerodynamic parameters are expressed as the explicit functions of the flow angle φ, the optimal design procedure and the computer program of the aerodynamic performance are very simple and the iteration in the conventional design method, can be avoided. The obtained results are accurate and reliable.
