| 中文摘要: |
| 基于计算流体力学,对离心泵叶轮内部流场进行了数值模拟。采用有限体积中心格式、时间推进解法以及N-S方程计算。得到了叶轮压力分布等值线、叶轮相对速度矢量以及二次流分布,并进行详尽的分析,揭示了叶轮内部流动情况,为优化叶轮设计提供了理论依据和技术保障。 |
| 英文摘要: |
| A numerical simulation of internal flow through a centrifugal pump impeller is made by the computational fluid dynamics technique.Using the central finite-volume scheme and the time-matching algorithm,the N-S equation is solved.As a result,we acquire the pressure distribution,the relative velocity vectors and the secondary flow of impeller.In addition,the internal flow through the centrifugal pump impeller is analyzed,the results of which will provide theoretical basis and technical support for optimizing the design of centrifugal pump impellers. |
