【摘要】 本文以离心风机叶轮为对象,通过理论分析并应用电子计算机,获得了一种对三维设计和一维设计离心风机叶轮子午流道形状均可适用的数值方法。与作图方法相比较,本数值方法能够简捷而准确地获得满足给定子午速度分布的叶轮子午型线。一次上机即可得到多个设计方案,便于设计者优化选择。因而具有很好的工程实用性。更多还原

【Abstract】 Through thcoretical analysis and computerization, this paper presents a nu-merical method suitable for both three-dimensional design and one-dimensionaldesign of the shape of impeller meridian passage in a centrifugal fan. By usingthe numerical method, the shape of impeller meridian passage at a given meridianvelocity distribution is obtained. The merit of the proposal computer programis such that several sets of results are obtained for choice each time theprogram is run on a computer. Hence the numerical design procedure is good forengineering application.更多还原
