Numerical analysis of cubage loss of centrifugal fan in power plant;

电厂离心风机容积损失的数值分析

In this paper 3-D numerical simulation of centrifugal fan is carried out with Fluent in order to investigate the inside flow field and cubage loss.

本文用FLUENT对离心风机蜗壳内部流场进行三维数值模拟,得到其流动特征及容积损失情况,针对模拟结果设计出不同型式防涡圈,对加装防涡圈后的离心风机进行数值模拟的结果表明加装防涡圈后的风机,其内部旋涡强度降低,流场流动得到改善,容积损失大为减少。
