Выдержка

Rarefied gas flow in two-dimensional (plain or axisymmetric) channel or nozzle at high Knudsen numbers is investigated numerically using direct statistical Monte-Carlo simulation. The computation time is reduced due to the expansion of the roughness operator which is applied to the scattering function on smooth surface giving as a result the expression of the scattering function on rough surface. The representation of the roughness operator is derived that is convenient to use both in numerical DSMC methods and in analytical investigations. The dependence of the macro-parameters of rarefied gas molecular flow on surface roughness of the walls and on geometrical shape of the channel is studied.
