ABSTRACT
Numerical analyses of the second-order Knudsen layer are conducted on the basis of
the linearized Boltzmann equation for hard-sphere molecules under the diffuse reflection boundary condition. These aim at completing the data for the asymptotic theory of the Boltzmann equation (the generalized slip-flow theory) that have been lacking for nearly a half century except for the Bhatnagar–Gross–Krook (or Boltzmann–Krook–Welander) kinetic model equation. Numerical data, except for the curvature effects, are prepared up to the second order in the Knudsen number expansion.
