EFFICIENCIES OF A NONMIXING (IDEAL) CASCADE AND A MIXING CASCADE WITH SEPARATION COEFFICIENTS DEPENDENT ON THE PARAMETERS OF A CASCADE STAGE

A comparison of the effi ciencies of the optimum mixing and nonmixing (ideal) cascades comprising stages, the coeffi cients of separation of a mixture at which are dependent on their parameters, has been performed. It was established that an optimized mixing cascade can have a smaller number of centrifuges, as compared to that of a nonmixing cascade, the separation capacity of whose stages deviate from the optimum one by 1–10%. For an optimum mixing cascade, this deviation is smaller, which can be explained by that the requirement for the fulfi llment of the nonmixing condition at the joints of fl ows in such a cascade narrows the area of search for the parameters of the cascade and thus excludes more eff ective variants of solving the separation problem.
