The dependence of the macro-parameters of rarefied gas molecular flow at high Knudsen numbers on surface roughness of the walls(see Ref.[1]) and on geometrical shape of the channel is investigated asymptotically and numerically using different models of surface roughness in statistical Monte-Carlo simulation.
