Abstract

The centrifugal separation of an initially homogeneous mixture of particles and fluid is considered in ‘long’ containers for which end-wall effects are negligible. The vorticity produced in the mixture region during separation is shown to be a function of time only. As a consequence, the ‘full’ nonlinear theory in such containers, of arbitrary cross-section, can be reduced to the determination of an appropriate analytic function. A problem of technological interest is discussed.
