Flow in Rotating Cylinder of a Gas Centrifuge
Journal of Nuclear Science and Technology, 1974 Thermal convection and weak forced flows in a rotating cylinder were studied theoretically to find the mass velocity distributions in a gas centrifuge. Compressibility of the gas is taken into account in the form of a density stratification in the radial direction.
