【摘要】

：

运用以渗透边界求解流场与追踪流线求解壁面为基本原理的反问题设计方法,对某带分流叶片的斜流压气机叶轮进行改型设计.以压力分布为给定参数,正问题流场为初始条件,求解得到新的叶片造型.针对由分流叶片前缘引起的主叶片载荷分布的变化,通过对主叶片压力面进行不同幅度的压力修改实现对主叶片载荷的改进,并分析主叶片载荷变化对叶轮性能的影响.改型后的斜流叶轮大小叶片载荷重新分配,部分改型叶轮性能得到提高,可为斜流叶

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.

可调进口导叶前缘几何的研究

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
