摘要
在对子午加速轴流风机级效率公式分析的基础上,考虑到叶轮内部的损失,应用最优化理论,进行了求解子午加速轴流风机叶轮叶片最佳扭曲规律的数值计算。还给出了子午加速风机最佳设计方法与常规设计方法对风机性能参数影响的实测数据比较。
Taking account of the loss inside a vane wheel, optimization technique isapplied to the numerical computation of flow type for meridionally-accelera-ted axial-flow fans on the basis of analyzing the stage-efficiency equation.The optimum flow type so determined is compared with the data measured ofcommonly-used flow type in current fan design for their different influences onfan's performance.
