摘　　要：基于提取的雀鹰、长耳鸮翅膀的表面特征对小型轴流风机的叶片进行仿生优化,以求提高风机的气动性能。设计出8种仿生风机模型,通过CFD计算选出最优的仿生风机模型进行性能试验验证,并与原型风机进行了对比。对比试验流量-静压曲线发现,仿生风机气动性能明显好于原型风机,最大质量流量提高了6.1%,最大静压提高了7.0%,并发现V型截面好于圆弧型截面。本研究为叶片仿生参数的进一步优化提供了前期基础。The surface characteristics of the wings sparrow hawk and long-eared owl were extracted and used to optimize the blade of small axial fan to improve aerodynamic performance of the fan.The best fan was selected from eight bionic axial fans using CFD method.Computer simulation analysis and aerodynamic experiments show that the flow-static pressure curve of the bionic blade fan is remarkable better than that of prototype fan.The maximum mass flow rate of the bionic fan is 6.1% higher than that of prototype fan and the maximum static pressure is 7% higher,respectively.Experiments also show that the V-section is better than arc-section of the blade.The study provides a preliminary basis for optimizing the parameters of the blade of bionic fan.
