摘要
为提高水翼抗空化性能,设计出具有较好空泡性能的翼型剖面,基于i SIGHT优化平台,集成翼剖面水动力性能的面元法理论预报程序,采用试验设计方法(DOE)构建剖面几何参数对翼剖面性能的响应面模型,分析剖面各几何参数对剖面空泡性能的影响。结果表明,增大剖面的最大拱度,最大厚度向导缘移动,最大拱度向尾缘移动以及减小攻角均有利于提高剖面的水动力性能;增加剖面的最大厚度能改善剖面的空泡性能,但剖面最大厚度一般根据剖面强度要求确定。
In order to improve the cavitation performance of the blade,a prediction program is developed based on the i SIGHT software and the panel method. The response surface model is established to analyze influence of the blade section parameters upon the blade performance by using the method of design of experiment（ DOE）. It is shown that the blade section parameters such as the maximum camber,maximum thickness,thickness and camber distributions,the angle of attack will affect the cavitation performance of the blade. Increasing the maximum thickness of the blade can improve the cavitation performance,while the maximum thickness should be determined by the requirements of strength of the blade.
