             abstract = "A computational investigation has been carried out to examine a 
                         rarefied hypersonic flow over cavities by employing the Direct 
                         Simulation Monte Carlo (DSMC) method. The work focuses on the 
                         effects in the aerodynamic surface quantities due to variations in 
                         the cavity length-to-depth (L/H) ratio. The results presented 
                         highlight the sensitivity of the heat transfer, pressure and skin 
                         friction coefficients due to changes on the cavity L/H ratio. The 
                         L/H ratio ranged from 1 to 4, which corresponded to overall 
                         Knudsen number KnL in the transition flow regime. The analysis 
                         showed that the aerodynamic quantities acting on the cavity 
                         surface rely on the L/H ratio. It was found that the pressure load 
                         and the heating load to the cavity surfaces presented peak values 
                         along the frontal face, more precisely at the vicinity of the 
                         cavity shoulder. Moreover, these loads are much higher than those 
                         found in a smooth surface.",
