摘　　要：应用粘性流体力学的基本原理,采用专业流体力学软件对复合材料风机叶轮内气流流动进行数值模拟,发现叶轮内气流流动状况不理想,据此对叶轮的叶片进行改进设计,得到了改进叶片设计后叶轮内的流场,改进了复合材料风机叶轮的结构,改善了叶轮内部气流的流动状况,提高了叶轮的气动性能,为研制出高性能的新型复合材料风机叶轮奠定了基础。With viseious fluid mechanics basic theory and CFD software, numeric simulation of air flow inside a composite fan impeller was made,and that air flow inside fan impeller was not good was found, so blades of the impeller were optimized to result in a better air flow and better aerodynamic properties,and to lay a good foundation for developing high performance new composite fan impeller.
