U.S.S.R. Comput. Math. Math. Phys. 30, No. 2, 193-195 (1990); translation from Zh. Vychisl. Mat. Mat. Fiz. 30, No. 4, 623-626 (1990).
Summary: The problem of stationary one-dimensional heat flow between parallel flat surfaces in a rarefied gas is solved using two independent numerical methods: the finite difference method of direct solution of the Boltzmann equation and the method of direct statistical simulation. By comparing the results, the accuracy of the methods is established and the algorithms for solving the problem are verified. The features of the flow are investigated for a wide range of Knudsen numbers.
