中文摘要:
      针对带管式减涡器的径向内流共转盘腔结构,为了研究导流管出口角度对盘腔内流场结构、压力损失的影响规律,数值 模拟了不同转速和出口角度下的盘腔内部流场,获得了不同工况下的总压损失分布柱状图。结果表明:在相同转速下,直管式与 60毅弯管式减涡器降低压力损失的效果相近,90毅弯管式降低压力损失的效果最好,30毅弯管式降低压力损失的效果最差;在所有转 速下,压力损失随出口角度的变化分布存在1 个最高点;增加转速,压力损失总体减小。
英文摘要:
      In order to study the influence of the outlet angle of the honeycomb duct on the disc cavities flow field structure and pressure loss in the co-rotating disc cavities for the radial inflow with tubed vortex reducer,the flow field in the disc cavities under different rotational speed and outlet angle was simulated numerical,and the histogram of the total pressure loss distribution under different working conditions was obtained. The results show that the effect of reducing pressure loss between straight pipe and 60 °curved tube is similar,90 ° bend pipe is the best,and 30 °bend pipe is the worst at the same speed. At all speeds袁there is a highest point in the distribution of pressure loss with the outlet angle. With the increase of speed,the overall pressure loss is reduced.
