| 摘 要： | 为研究高速部分流泵由于叶轮和蜗壳的动静干涉而产生压力脉动情况,采用Fluent 6.3软件中S-A湍流方程和滑移网格技术(SM),分别选取直叶轮和复合直叶轮,在设计工况点进行非定常的数值模拟,分析中间截面总压和静压分布云图,发现复合直叶轮的总压高于直叶轮,而静压相近;在出口和蜗壳内壁圆周的0°,90°,180°和270°处布置4个监测点,比较总压脉动情况看出,复合叶轮的峰值明显高于直叶轮,而峰值之间的波动幅度要比直叶轮的小.

| Abstract: | To study the pressure pulsation caused by the interference between the rotating and static portion,i.e.an impeller and a volute in a high speed portion flow division pump by using the S-A turbulent flow equation and sliding grid technology in software Fluent 6.3,a straight impeller and a complex one were chosen respectively.An unsteady numerical simulation was performed at the design operating point to analyze the total pressure and static pressure distribution chart in the middle section.It has been found ... |
