| Abstract: | The temperature distribution in a rotor of a single centrifuge should be investigated to improve the centrifuge performance. A gas centrifuge rotor made of two layers of materials was analyzed using the finite element method with isoparametric quadrilateral elements with four nodes. The numerical analysis was used to predict the centrifuge rotor temperature field for different conditions for two dimensional axially symmetrical steady state condition. The results are compared with experimental data. |
