Abstract
One consider a method for solving the Boltzmann kinetic equation for a gas flow which is close to the local thermadynamic equilibrium. To eliminate the “stiffness” of the equation, a special method for evaluation of the collision integral is developed. The numerical algorithm uses the splitting on a relaxation and on a transport stages. The scheme for the relaxation stage is conservative and gives correct asymptotic solution when the time stepτ→∞. For the transport stage the conservative flux-corrected scheme is applied. Some examples of calculations are presented.
