【摘要】

：

利用NUMECA软件对具有不同前缘几何形状的压气机可调进口导叶的二维叶型做了数值模拟,得到了不同的叶型在不同的安装角和不同的来流马赫数下的流场和气动特性.结果显示对于前缘半径较大的叶型,在导叶安装角较小的工况下有较小的流动损失;对于小前缘半径叶型,在导叶安装角较大的工况下有较小的流动损失;但是过大的前缘半径则会带来更大的损失.说明可调进口导叶设计中应充分考虑工况来选择前缘几何,若导叶安装角变化范围

叶轮泵中旋转空化机理及影响因素的研究进展

旋转空化是一种两相非定常现象,分为三类:超同步旋转空化、同步旋转空化、次同步旋转空化.本文阐述了旋转空化发生的典型特征:起始取决于空化数与2倍入射角(σ/2θ)的比值;扬程下降迟缓,产生轴振动(一种自激振动).影响旋转空化的因素有:空化数、入射角、空穴长度、热力学等.此外,理论推导了B因子和热力学参数Σ.
