Optimal working regimes of the hyper-speed long Iguasu gas centrifuge
© 2020 Published under licence by IOP Publishing Ltd.Rapid development of technologies for production of new materials may provide design of gas centrifuges (hereafter GC) with rotor speed above 1000 m/s. The question about efficiency of such GCs remains open. At present no experimental or theoretical studies regarding the separation effciency of such GCs exist. We present the results of calculations of the optimized separative power of the hyper-speed Iguassu GCs with a length of 1 to 5 meters and rotational speeds from 1000 to 1500 m/s. The calculations were performed in axisymmetric approximation in frameworks of the source-sink model. It is shown that for the hyper-speed GCs the optimized separative power, pressure at the rotor wall, feed flux and gas friction power linearly grow with the rotor length, while the temperature drop along the rotor does not depend on the rotor length.

Three-dimensional modeling of the flow around the gas scoop under optimal working regime of the Iguassu gas centrifuge at the hyper fast rotation
© 2022 Institute of Physics Publishing. All rights reserved.The problem of the gas withdrawal from an Iguassu gas centrifuge (GC) at the speed of rotation, over 1000 m/s is considered. We focus our attention on the problem of achieving of optimal waste flow and friction power of the gas scoop simultaneously. Calculations were carried out in a three-dimensional approximation for supersonic flow of UF6 around a stationary gas scoop taken as a Pitot tube with a diameter of 2 mm. Attempts to achieve the optimal working regime of GC for the selected particular gas scoop were not successful. On the basis of this results we conclude that the optimal gas withdrawal and creation of the optimal axial circulation can be problematic for the hyper-speed gas centrifuges.
