本文介绍一种具有后掠叶片的径流式压气机叶轮造型方法。对用这种方法形成的一组叶轮,用准正交面方法计算它们的三元流场,发现其流场具有逆压力梯度较小等优点。并对后掠叶片叶轮流场好的原因作了分析。
This article describes a method of modeling a radial compressor impeller with a swept-back blade. For a group of impellers formed by this method, their ternary flow field is calculated by quasi-orthogonal surface method and the flow field has the advantages of smaller inverse pressure gradient. The reason of the good flow field of the blade of the swept vane is analyzed.
