摘要：

We present the DSMC analysis of the motion of a small spherical particle in a circular micro-pipe filled with gas molecules with given number density. We simulate a variety of steady-state flow regimes: from free molecular to near continuum. Drag and Brownian force are computed for different particle and pipe sizes.
