The vortices flow in the blade passages and the influence of the eccentric inlet of the multi-blade centrifugal fan for air-conditioner have been analyzed numerically by using commercial CFD code.
本文采用CFD方法，详细分析了空调用多翼离心风机叶道中的气流分布以及进气口偏心的影响。
Vortexs are observed after the beams, which greatly influence the inlet air-flow of fan, reduces the air-flux, causes noise and wastes energy.
支承结构造成的流体绕流现象在风机进口处形成涡流，造成风机风量减少，噪声增加，浪费能源。
The result is that from inlet to outlet of the blade channel, Axial fan blade effected on air flow is a gradually changed process of energy transmitting.
结果表明，从叶道的进口到出口，轴流通风机叶片对气流的作用是一个渐变的能量传递过程。
It shows that the flow field in the inlet box of a centrifugal fan can be simulated successfully with the algorithm described in this paper.
这表明，该算法可以较好地模拟离心式风机进气箱内气体的流动，其计算结果可为进气箱的设计和改造提供参考。
A numerical simulation of the three-dimensional steady flow field in the whole flow field, from the inlet of the collector to the outlet of the diffuser, a 2k70 axial-flow fan is performed.
