abstract = "This work describes a computational analysis of a hypersonic §ow
over a combined gap/step con¦guration at zero degree angle of
attack, in chemical equilibrium and thermal nonequilibrium. E¨ects
on the §ow- ¦eld structure due to changes on the step frontal-face
height have been investigated by employing the Direct Simulation
Monte Carlo (DSMC) method. The work focuses the attention of
designers of hypersonic con- ¦gurations on the fundamental
parameter of surface discontinuity, which can have an important
impact on even initial designs. The results high- light the
sensitivity of the primary §ow¦eld properties, velocity, density,
pressure, and temperature due to changes on the step frontal-face
height. The analysis showed that the upstream disturbance in the
gap/step con- ¦guration increased with increasing the frontal-face
height. In addition, it was observed that the separation region
for the gap/step con¦gura- tion increased with increasing the step
frontal-face height. It was found that density and pressure for
the gap/step con¦guration dramatically increased inside the gap as
compared to those observed for the gap con- ¦guration, i. e., a
gap without a step.",
