| Numerical simulation of a binary gas flow inside a rotating cylinder A. A. Ganjaei, S. S. Nourazar
The Journal of Mechanical Science and Technology, vol. 23, no. 10, pp.2848-2860, 2009
Abstract : A new approach to calculate the axially symmetric binary gas flow is proposed. Dalton’s law for partial pressures
contributed by each species of a binary gas mixture (argon and helium) is incorporated into numerical simulation of
rarefied axially symmetric flow inside a rotating cylinder by using the time relaxed Monte-Carlo (TRMC) scheme and
the direct simulation Monte-Carlo (DSMC) method. The results of flow simulations are compared with the analytical
solution and results obtained by Bird [1]. The results of the flow simulations show better agreement than the results
obtained by Bird [1] in comparison with the analytical solutions. However, the results of the flow simulations using the
TRMC scheme show better agreement than those obtained using the DSMC method in comparison with the analytical
solutions.
