通过双时间步求解三维非定常N-S方程,获取多级压气机内部非定常流场细节,为深刻认识多级、逆压环境下叶轮机内部非定常流动特征,进而提高其性能提供有益参考,分析结果表明:动/静叶排相干对下游静子叶片表面压力分布影响随着半径增大而增大;当上游尾迹输运至下游叶片通道时,低能量气流团将会充分与主流掺混,可能导致损失增加,当上游尾迹区域输运至下游静子前缘时,对应的叶栅通道低马赫数区域相对较小;由于下游静子叶片的位势作用,其对上游转子叶片尾缘流动结构产生较大影响,随着流面半径增大,下游叶片对上游流场的位势作用愈明显,非定常分离流动形式差别愈大。
补充资料:多级转鼓活塞推料离心机
分子式:
CAS号:
性质:又称多级推料离心机。与单级或双级推料式结构原理相等,仅增加了转鼓数目,图为四级转鼓离心机。一级、三级转鼓与推料杆连接,二、四级和推料盘与空心主轴连接。推料杆向左运动时,一、三级转鼓上物料被推到二、四级转鼓上。推料杆向右运动时,二、四级转鼓物料被推到三级转鼓和出料腔。物料停留时间长,又多次被松动是多极转鼓的优越之处。适于处理物料粒度细、摩擦大和双级推料离心机难以处理的物料(图暂缺)。
