弹跳

The calculation results shows that ,(1) when the rotor rotates at the working speed, a local regurgitant whirlpool that is rightabout to the rotor"s rotating direction appears in the classifying region, which makes the separated granules come back to the outside of the classification district and influences the classification efficiency of the turbine classifier;(2) in the condition of a low rotating speed of turbo rotor, ultrafine particles can follow the gas phase by and large, but when the rotating speed increases, a phenomenon of velocity slippage between two phases appears evidently;(3) A operating parameter, air flow rate is so important that can directly influence the stability of flow field in classifying chamber, the bigger the air flowrate is , the steadier the flow field is;(4) Compared with straight blades, the new shape of blades with backward crooked elbow are helpful to improve the stability of flow field and form whole stream easily, also beneficial to advance the classification accuracy and classification efficiency;(5) The motion trace of particles are very complicated when the turbo rotor rotates at a high speed, the constant bounce of the particles appear between the blades and the coarse particles are even bounce back from the inlet, only the finer can pass through the classification area from the oulet;(6) Along with the increase of the rotor"s rotating speed, radiah axial and tangential velocity all begain to fluctuate repetitively like sine-wave, the smaller the particles are, the more violently they fluctuates.

数值模拟结果表明，(1)在涡轮达到工作转速时，在分级区域形成了一个与涡轮旋转方向相反的局部回流涡，它使得分离出来的细粒重又被带回分级轮外边缘，从而严重影响分级机的分级效率；(2)粉尘粒子在涡轮低速运动情况下，基本上能跟随气体运动，但随着转速加大，两相之间出现了明显的速度滑移现象；(3)分级机工作时的风量也是一个比较重要的操作参数，它可以直接影响到分级机内腔流场的稳定性，风量越大，流场越稳定；(4)同直叶片形状相比较，带后弯导板的叶片，有利于改善流场的稳定性，流场容易形成整体流，对提高分级效率和分级精度都非常有利；(5)粒子轨迹线在涡轮转速较高时十分复杂，有的出现了反复的弹跳现象，大颗粒不能通过分级区域而从进口返流了，只有细小的颗粒才从出口处流出；(6)涡轮转速加大时，粒子的径向、轴向和切向速率出现了明显的类似于正弦波的脉动现象，颗粒越小，脉动程度越为剧烈。

Uhoo Uhooo uhoo uhoo But I'm getting stronger and stronger Uhoo Uhooo uhoo uhoo But I'm getting stronger and stronger Midnight turns to morning, I don't get lot sleep I know that you are out there somewhere, being someone else's treat Have think us knows just how to please me Chance run down my spying And when you wake up spill your kisses, I am shivering inside it I get my Inside out, and my headache won't stop I fail to not look back, as I'm bouncing down the wrong track Half way up your smile going down, but I'm getting stronger and stronger.

uhoo uhooo uhoo uhoo 但我越来越强 uhoo uhooo uhoo uhoo 但我越来越强午夜轮流今天上午，我不得到很多睡眠我知道你是那里的某处，被别人的治疗有认为我们知道如何请我运行的机会，我的谍报活动当你醒来泄漏你的亲吻，我寒战内我的内，和我的头痛就不会停止我无法不回头看，作为我弹跳下来的歧途中途你的微笑去，但我越来越强。
