摘要
基于叶素-动量理论,采用Wilson修正计算模型,编写了叶片优化计算的MATLAB程序,获得了计算弦长和扭转角,并进行了修正;通过坐标变换可得出叶片截面的空间坐标,导入Pro/E中,从而实现了叶片及叶轮的程序化设计和三维造型;采用双转子结构应对潮流周期性往复运动的特点,提高了潮流能的利用率,且结构简单,便于应用。
Based on blade element-momentum theory and adopted Wilson correction calculation model, the Matlab program of blade optimization was wrote. The ideal chord and torsion angle was calculated and amended. The space coordinates of blade sections was obtained by coordinate transformation and imported into Pro/E, thus programming and three-dimensional modeling of the blade and impeller were achieved. Dual-rotor structure was applied to deal with the characteristics of tide periodic reciprocating motion and improve the energy efficiency. The structure was simple and easy application.
