中文摘要	Three dimensional Navier-Stokes equations were solved using Finite Volume Method to study the flow around the scoops in a gas centrifuge. The second order up-wind implicit scheme was adopted to efficiently. Parallel calculation was performed on a cluster parallel computer capture the shock-wave field around the scoop using a circle chamber model, and the to simulate the supersonic flow-field distribution was obtained. The results indicate that a strong detached shock forms in front of the scoop. As the radial position increases, the shock is stronger and the distance to scoop surface is smaller. An oblique shock forms between the scoop and the centrifuge wall; behind the shock, the radially inward motion of gas is induced because of the imbalance of the pressure gradient and centrifugal force.
