|
摘要
基于风机行业多年前联合设计开发的5-29离心风机气动参数,设计出新型5-29离心通风机。通过Solidworks软件建模,CFX软件进行气动计算分析,调整了b_1/D_1值、叶片出口角、蜗壳宽度等参数。优化后的最终风机模型,流场中边界层分离和环流损失均较小。具有效率高、高效运行区宽广、性能曲线平坦等特点。CFD计算值和实测值基本吻合,实测最高效率高达85.2%,高出国家一级能效等级标准6.2%。
In this paper, a new 5-29 centrifugal fan was designed which was used solidworkds software to built the fan model and CFX software to simulate the aerodynamic of fan. The new model have minor losses in separation boundary layer and circumfluence flow by adjusted the b_1/D_1 value, the outlet angle of blade, the width of volute. The new fan model has high efficiency, wide running area and flat curves. The new fan efficiency 85.2% is higher 6.2% than standard of Chinese first stage energy efficiency.
