| 摘 要： | 本文对三元扭曲叶片叶轮离心风机内粒子运动轨迹及叶轮磨损情况进行了理论分析和实验研究。考虑风机叶片的三元扭曲特性,推得一整套三元扭曲叶片粒子反弹的计算公式.对三元扭曲叶片和单圆弧叶片的碰点分布进行了计算比较,前者比后者的分布均匀程度有所改善。用靠背管测量含尘与不含尘时的风机特性是可行的.试验证明,本文所用的两相流物理模型,其理论计算与试验结果有很好的一致性,对设计和制造耐磨性较好、效率较高的风机有一定的实用价值.

| Abstract: | The particle trajectories and the impeller erosion in a centrifugal fan with 3-D twisted blades are studied theoretically and experimentally.With the aid of 2-D rebounding experimental formulas,a set of calculation formulas for 3- D twisted blade particle rebounding is worked out.Compared with the single-curved blade,the uniformity of encountering points of the 3-D twisted blade is better.The performance of the fan,whether it is exposed to particle flow or not,can be measured successfully with back to back probe.The theoretical calculation agrees well with the experiments and it is proved that the two-phase flow model used in this paper is feasible in the design and manufacture of the fans with higher efficiency and better resistance to wear. |
