%X Numerical simulations of two-dimensional steady-state rarefied hypersonic flow in a gap at different length-todepth (L∕H) ratio are performed by using the direct simulation Monte Carlo (DSMC) method. The work focuses on the effects in the aerodynamic surface quantities, such as heat transfer, pressure, and skin friction coefficients due to variations in the gap L∕H ratio. The analysis showed that aerodynamic surface quantities presented a large dependence on the L∕H ratio for the range investigated. It was found that heat transfer, pressure, and skin friction coefficients presented the maximum values along the gap downstream face, more precisely, at the vicinity of the gap shoulder. Furthermore, simulations showed that pressure and heating loads are larger than those for a smooth surface, for the conditions investigated.
