通过对Eckardt离心叶轮数值计算与实验结果的对比,分析半开式离心叶轮内部二次流的形成机理与分布,建立基本的半开式离心叶轮内部三维二次流模型;基于该二次流模型,对射流尾迹结构的特点与形成机理进行了详细的分析和说明。
Based on the comparison of numerical and experimental results of Eckardt centrifugal impeller, the formation mechanism and distribution of secondary flow in semi-open centrifugal impeller are analyzed and the basic three-dimensional secondary flow model of centrifugal impeller is established. Based on the secondary flow model , The jet wake structure characteristics and formation mechanism of a detailed analysis and description.
