摘要
一、方法概述 本方法大体包括以下三个方面的内容: 1.级数展开法反问题 级数展开法的本质,是由给定流线上的一维流动出发,通过向另一向的台劳级数展开而得到二维流场。沿流线可以考虑熵增以表征流动损失。为了简化,假定沿另一方向熵的变化为零,即。
In order to develop a CAD computer code system for centrifugal compressor, a numerical technique for design and flow analysis of vaned diffusers has been introduced in this paper. The design of diffusers has been performed by a streamline extension method. The velocity and pressure distributions at design and off-design operating modes have been calculated by a lime-dependent finit difference scheme and have been corrected by boundary layer calculations. The numerical results are compared with experimental measurements, and the agreement is satisfactory.
