摘要：

The time step truncation error in direct simulation Monte Carlo calculations is found to be O(Delta t(2)) for a variety of simple flows, both transient and steady state. The measured errors in the transport coefficients (viscosity, thermal conductivity, and self-diffusion) are in good agreement with predictions from Green-Kubo analysis [N. Hadjiconstantinou, Phys. Fluids 12, 2634 (2000)]. (C) 2000 American Institute of Physics. [S1070-6631(00)00110-0].
