離心式水幫浦CFD及葉片最佳化設計

Abstract

本研究主要目的在於分析葉片設計參數對離心式水泵浦之性能的影響，並對葉片設計作最佳化。利用CAD所建立之模型以CFD套裝軟體ADINA作數值計算，分析其流場現象與性能曲線。然後以數值方式分析不同葉片入口角、葉片出口角及葉片數對離心式水幫浦的性能影響。

This research is aimed to analyze the effects of different blade design factors on the performance of centrifugal water pump in order to obtain the optimum design to the blades. The velocity field of the working fluid and the performance curve of the numerical model established by CAD are calculated by using CFD software ADINA. In the simulation, the efficiencies of centrifugal water pump with different blade inlet angle, blade outlet angles, and blade number are also obtained and analyzed.
