Determining Dependency of Gas Centrifuge Separation Factor to Some Principals Parameters

For increasing isotopic separation power of a gas centrifuge, the axial circulating flows are created by mechanical or thermal drives. In this paper, the feed injection (mechanical drive) and the axial temperature gradient (thermal drive) are used to induce an internal circulating flow and a model is applied as a governing differential equation of the gas motion. The outcoming of the purely axial flow model is used along with the diffusion equation to obtain concentrations of different isotopes at the gas exodus orifices. The machine separative factor is obtained after specifying xP (the product concentration of lighter isotope) and xW (the waste concentration of lighter isotope) from the enriching and stripping sections. Finally, the dependency of the separative factor to rotor speed, cut and feed flow rate was investigated.
