Numerical studies are performed of the separation of a model multi-component isotopic mixture in a three-stream cascade. The particulars of isotope accumulation as a function of cascade shape (length, stage distribution of interstage flow) are examined. The regularities of the effect of the cascade shape on the component concentration in the cascade holdup are determined. An enriched isotopic mixture can be obtained by accumulation and partial removal of the process gas from the stages where the target component concentration is highest.

分离级联形状对级联滞留中同位素混合物浓度的影响

对三流级联中模型多组分同位素混合物的分离进行了数值研究。检查作为级联形状（长度、级间流动的级分布）的函数的同位素积累的细节。确定了级联形状对级联滞留率中组分浓度影响的规律。通过从目标组分浓度最高的阶段积累和部分去除工艺气体，可以获得富集的同位素混合物。
