摘　　要：针对隧道活塞风引起的射流风机喘振问题,介绍了一种简易的射流风机防喘振装置。运用F luent软件对改进前后的射流风机流场进行了数值模拟并进行了对比,结果表明这种防喘振装置能有效的改善风机内部流场,是有效的防喘振措施。Against the surge problem of the jet fan influenced by the piston wind in channels, an anti-surge equipment is introduced. The flow fields of the jet fan both with and without anti-surge equipment is simulated via the software of Fluent. A comparison is also carried out between two flow fields. The results of the simulation show that the anti-surge equipment can improve the flow field of the jet fan substantially. So this anti-surge equipment can prevent the surge of the jet fan effectively.
