In the vortex separation process a mixture of uranium hexafluoride gas and hydrogen is injected tangentially into a tube, at one end through nozzles or holes at velocities close to the speed of sound the tube tapers to a small exit aperture at one or both ends.
A mixture of uranium hexafluoride gas and hydrogen is injected tangentially into a tube. This was in the vortex separation process. This is at one end through nozzles or holes at velocities close to the speed of sound. The tube tapers a tube to a small exit aperture at one. The tube tapers a tube to a small exit aperture at both ends.
