Abstract
In the present paper, the axially symmetric rarefied gas flow inside a high-speed rotating cylinder has been investigated numerically using a new algorithm, a DSMC code modified with the consistent Boltzmann algorithm (CBA), and the Direct Simulation Monte Carlo (DSMC) method. The Argon rarefied gas is supposed to be contained in a rotating cylinder which rotates with angular velocity of 15,000 Rad/s. The results of the flow simulation using the CBA scheme and the results of the DSMC method is compared with, the analytical solution and the numerical results of Bird (Molecular gas dynamics and the direct simulation of gas flows. Oxford University Press, London, 1994) for verification the accuracy and validity of the results of the present work. The results of numerical simulation were in a good agreement with available results. Also the results of the flow simulations using the CBA scheme show better agreement than those obtained using the DSMC method in comparison with the analytical solution.
