A numerical method was developed to calculate the distribution of concentration of 235UF6 in the rotating cylinder of a centrifuge. Satisfactory convergence was obtained by employing the formulation of convective terms devised for the computation of high Reynolds number flow. Moreover, the pressure diffusion term was linearized and approximated by a constant value, which significantly reduced the number of cases to be run on a computer. The results of numerical analysis for a centrifuge of counter-flow type are shown, and the effect brought upon the separative efficiency by changes in various parameters is discussed. The results of the present analysis are compared with those obtained from the existing theory, and the reasons for the discrepancy between the two results are explained. Finally, it is shown that the results of the numerical analysis agree well with the experimental data obtained previously by Beams et al.
