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 efficiencies of the optimum mixing and nonmixing (ideal) cascades comprising stages, the coefficients 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 fulfillment of the nonmixing condition at the joints of flows in such a cascade narrows the area of search for the parameters of the cascade and thus excludes more effective variants of solving the separation problem.
