摘要
采用流场结构分析和叶片造型调整结合的全三维优化设计方法,对可逆式轴流通风机进行了优化设计,并对样机进行了性能验证实验.结果表明:在不改变风机外径、转速和间隙的情况下,风机的性能得到大幅改善.风机的内部流场合理,没有明显的分离和回流;风机的性能曲线比较平滑,变工况性能好;经性能实验验证,优化设计后的风机各项指标均达到了设计要求.
Optimization design of a reversible axial fan was conducted by the method of three dimensional optimization design based on the flow analysis and blade profile modification, validation tests were conducted on a sample fan as well. The results show that the performance of the fan is improved significantly without changes of diameter, rotation speed and clearance. The internal flow field of the fan is reasonable without obvious separations and back flows. The performance of the fan at different flow rate is fine with the smooth performance curves. The three dimensional optimization design of the axial fan is successfully validated by the experimental results.
