【摘要】 离心级联中总是存在水力学的动态过程,减少动态过程对分离的不利影响或者利用动态过程提升分离性能是值得研究的课题。针对离心分离级联,给出了包括单向关联型离心机、供料和取料部分的动态水力学模型。为简明起见,忽略了其他部件如压缩机、管道、调节器等的动态模型。在给定模型方程中系数的情况下,可像研究扩散级联动态水力学过程一样,分析离心级联的动态水力学过程。更多还原

【Abstract】 Dynamic hydraulic process in a gas centrifuge cascade always exists.It is worth investigating the ways of mitigating negative effects of the process on separation performance or exploiting the process for better separation performance.Here a dynamic hydraulic model for centrifuge cascade is presented,including the centrifuges of the so-called uni-directionally connected type, feed and withdrawals.For the sake of simplicity,other components such as the compressors,pipelines, and regulators are ignored.Given the coefficients in these model equations,the dynamic hydraulic process in a gas centrifuge cascade can be analyzed in the same way as that of the dynamic hydraulic process in a diffusion cascade.更多还原
