Three-dimensional modeling of the flow around the gas scoop under optimal working regime of the Iguassu gas centrifuge at the hyper fast rotation

Abstract

Abstract 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 UF 6 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.
