abstract = "This paper describes a numerical study on backward-facing steps
situated in a rarefied hypersonic flow by employing the Direct
Simulation Monte Carlo (DSMC) method. The work is motivated by the
interest in investigating the step-height effect on the
aerodynamic surface quantities. In this fashion, the primary aim
of this paper is to examine the sensitivity of the heat transfer,
pressure and skin friction coefficients with respect to stepheight
variations. The analysis showed that the hypersonic flow past to a
backward-facing step is characterized by a strong expansion around
the step corner, which influences the aerodynamics surface
properties downstream its back face. It was also found that
changing the step height affected the aerodynamic surface
quantities a distance of a few mean free paths upstream of it.
Numerical results were compared with available experimental data
of surface heat flux downstream of the step, showing a very
reasonable agreement within experimental uncertainty.",
