轴流风机的进口径向畸变研究
Investigation on the inlet radial distortion of axial-flow fan

摘要: 对轴流风机的进口速度畸变情况进行了分析,利用改进的双激盘理论通过进口速度分布的改变来分析进口畸变对于性能的影响,并且将模型的计算结果与实际的实验结果相比较,得到一种合理的速度分布.Abstract: The inlet velocity distortion was analyzed by di-actuator theory in this paper.The research on the inlet distortion was implemented by changing the inlet velocity distribution via di-actuator theory.The computational results were compared with the experimental results,and then a rational velocity distribution was obtained in this paper.
