Abstract: A supersonic flow around a cylinder is studied by the direct statistical Monte Carlo method in a wide range of rarefaction: from regimes close to continuum to free-molecular flow. The effect of the accommodation coefficient on the flow near the cylinder and on heat transfer between the gas and the cylinder is examined.

Keywords: supersonic flow, flow around a cylinder, heat transfer, direct statistical Monte Carlo (DSMC) method, accommodation coefficient.
