| 摘 要： | 射流风机已在公路隧道、铁路隧道及地铁通风中被广为应用.正确的进行射流风机的空气动力设计可以提高通风装置效率,降低隧道通风的运营成本.通过对射流风机的空气动力特性分析,论证了射流风机叶轮所产生的静压仅仅是用于克服风机本身的内部流动阻力,与改善隧道内通风状态无关.指出在进行射流风机空气动力设计时,应使得其叶轮产生的静压尽可...

| Abstract: | Jet fan in road tunnels,railway tunnels and subways are widely used in ventilation.It is obvious that rational aerodynamic design of jet fan can improve efficiency of jet fan,and reduce operating costs of tunnel ventilation.Through jet fan aerodynamics analysis it was demonstrated that static pressure generated by jet fan impeller is merely useful for overcoming its own internal flow resistance and can not improve ventilation state of tunnel.It was pointed out that in the aerodynamic design process,static p... |
