| 摘 要： | 为探求某机车用轴流式风机的系统性能,对不同工况下带有前后导叶的该风机内部流场进行了数值仿真.模拟结果表明,在叶片转速不变情况下,随着气体流量的增加,叶片的气动压力增加,功率增大,风机的效率也随之提高;在气体流量保持不变时,随着叶片转速的增加,叶片的气动压力增加,功率增大;当风机出口存在阻力时,则叶片的气动压力增加,功率也增大.研究还表明,叶片两侧的最大气压差可达10 500 Pa以上,高速旋转时对叶片有一定危害.计算结果与试验测试结果的对比表明,二者吻合较好.

| Abstract: | In order to explore performances of some locomotive axial fan,the inner flow field of the fan containing front and back guide blades is simulated in different operating conditions.The results show that pneumatic pressure of the aerodynamic blades are increased with flow rate increase,and the power and efficiency are also enhanced when keeping constant rotate speed of the fan.Pneumatic pressure of the aerodynamic blades and the power are increased with increasing rotate speed of the fan,when the flow rate is... |
