Investigation the effective factors on the forces acting on the scoop in a gas centrifuge machine in three-dimensional conditions with the DSMC method

Abstract

This article presents a simulation of a scoop inside the rotor of a gas centrifuge machine in three dimensions. The scoop inside the centrifuge machine is 3D and curved in shape. Therefore, a 3D simulation is necessary to analyze the proper flow behavior around the scoop. For this purpose, using the results of this simulation, the flow around the product and waste scoops has been investigated in three dimensions. As a result of simulation in the scoop area of the waste and product under operating conditions of pressure and temperature, it was observed that the values of these forces are directly related to the distance between the scoop and the wall, and the drag force values differ between these two areas. According to the investigations, the differences in drag force values between product and waste scoop areas can be explained by the effects of pressure, temperature, and velocity of gas molecules. There is a direct relationship between these effects and the coefficients of adaptation of momentum as well as the difference between the rotational velocity of the fluid around the scoop and the rotational velocity of the scoop per height (duѲ/dz).
