             abstract = "This paper presents the results of a numerical study of hypersonic 
                         gap flow in the transition flow regime by using the Direct 
                         Simulation Monte Carlo (DSMC) method. The sensitivity and 
                         characteristics of the flowfield structure are examined by varying 
                         the freestream Mach number and the gap length-to-depth (L=H) 
                         ratio. The proposed work focuses on the effect of the primary 
                         properties, velocity, density, pressure and temperature, due to 
                         variations in these two properities, i.e., freestream Mach number 
                         of 5, 15 and 25, and gap L=H ratio of 1, 1/2, 1/3, and 1/4. Some 
                         significant differences in the gap flow topology were noted 
                         between transition flow regime and continuum flow regime. For the 
                         conditions investigated, it was found only one vortex core inside 
                         the gaps instead of a column of vortices usually observed inside 
                         the gaps in the continuum flow regime. The analysis showed that 
                         the primary properties behavior inside the gaps for Mach number of 
                         5 differed markedly from those for Mach number of 15 and 25. 
                         Conversely, the behavior of the properties for Mach number of 15 
                         is similar to that for Mach number of 25.",
