摘　　要：【目的】设计高压高效的大型船用轴流风机。【方法】首先以CLARK-Y翼型作为基本翼型,采用孤立翼型设计法,将压缩机载荷控制法应用于轴流风机叶片设计;然后根据《工业通风机用标准化风道性能试验》中的C型装置,建立轴流风机的仿真计算模型,基于雷诺平均法的k-ε湍流模型对初步设计的风机进行数值模拟,通过流场计算并结合轮毂的强度校核确定叶片弦长和叶片数;最后在C型风机性能测试试验装置上对其进行试验验证。【结果】在设计工况点试验的静压为420 Pa,全压达580 Pa,全压效率达83.8%。【结论】本研究结果可为后续其他风机的设计奠定基础,为高效高压大型风机的设计和研发提供一定的理论依据与参考。[Objective]A high-pressure and high-efficiency large marine axial flow fan was designed.[Method]First,the CLARK-Y airfoil served as the basic airfoil with an isolated airfoil design method adopted,by applying the compressor load control method to the design of axial flow fan blade;then,based on the C-type setup in the Standardized Duct Performance Testing for Industrial Ventilators,a simulation model of the axial flow fan was established so that numerical simulations of the preliminary fan design were performed by using the k-εturbulence model based on Reynolds-averaged methods,and through flow field calculations and strength checks of the hub,the blade chord length and number of blades were determined;finally,the fan was experimentally verified on the testing setup of C-type fan performance.[Result]At the design operating point,the static pressure is 420 Pa and the total pressure reaches 580 Pa,with the total pressure efficiency of 83.8%.[Conclusion]The results of this study can lay a foundation for the follow-up design of other models of fans and offer theoretical guidance and reference for the design and development of high-pressure and high-efficiency large fans.
