The effect of the gas-surface interaction model on the rarefied gas flow between parallel plates is investigated on the basis of the Boltzmann kinetic equation. The Cercignani-Lampis model for diffuse scattering with incomplete energy accommodation is provided as the boundary condition on plates. The numerical analysis of the heat transfer problem between parallel plates with uniform and sinusoidal temperature distributions is carried out. The computational algorithm is adopted for solving the Boltzmann equation onto Graphics Processing Units (GPUs). The speedup of the GPU-accelerated computation is 50 times as compared to CPU one. It was found that nonuniform temperature distribution on the plates induced a steady flow. In addition, the flow field strongly depends on the value of the accommodation coefficients imposing in the Cercignani-Lampis model and this effect is more visible for high Knudsen number. Presented results are in agreement with ones obtained by means of the direct simulation Monte Carlo method in [1].
