The gas behavior within a centrifuge machine could be divided into molecular and continuum. The Boltzmann equation solving is a precise method in the molecular region (feed entrance area). DSMC method is one of the Boltzmann equation solving methods. So far, the mass source used in the Onsager-Pancake equation in the continuum region has been an assumed source and many scientists have presented a different assumed mass source. It was calculated feed reaching form to continuum region and its effect on the border between the two areas in the mass source form using the direct Monte-Carlo method in this paper. Furthermore, it was compared with the Gunzburger's assumed mass source. Then, the mass source obtained from the presence of hydrogen fluoride light gas in the feed was calculated at the two regions border as a two-component mixture (ZUF6=0.97, ZHF=0.03), (ZUF6=0.93, ZHF=0.07) and (ZUF6=0.9, ZHF=0.1). The concentration distribution along the rotor was calculated through inserting the obtained flow function into the Onsager-Cohen diffusion equations. Finally, the separation parameters and power were calculated. Results indicated that separation factor and power decreases through increasing the light gas amount in the feed entering the machine.
