摘　　要：探讨了轴流通风机的设计方法,并用于煤矿防爆主扇轴流通风BK40-4№10的节能降耗改造,保持原通风机的集流器、机壳、扩散筒不变,重新设计了通风机叶片,并应用计算流体力学软件模拟了风机的性能。This article focuses on the design method of axial-flow fan. For the purpose of energy-saving, this design method is used in redesigning the main axial-flow fan, BK40-4-No10, that is against explosion for coal-mine. The original collector, casing and diffuser hold of fan are remained, while blade is redesigned and performance is simulated using Computational Fluid Dynamics (CFD).
