                         incidence is investigated for a range of body surface temperature 
                         from 440 to 1100 K.. The work is motivated by interest in 
                         assessing the overall performance of flat-nose leading edges in 
                         order to consider them as possible candidates for blunting 
                         geometries of hypersonic configurations. The Direct Simulation 
                         Monte Carlo (DSMC) method has been employed in order to examine 
                         the flowfield structure around these leading edges. A very 
                         detailed description of the primary flow property behavior 
                         immediately adjacent to the body surface has been presented by a 
                         numerical method that properly accounts for non-equilibrium 
                         effects arising near the leading edge and that are especially 
                         important at high Mach number. The results presented highlight 
                         some significant differences on the flowfield properties due to 
                         variations on the nose thickness and on the wall temperature. It 
                         is found that the upstream effects have different influence on 
                         velocity, density, pressure and temperature along the stagnation 
                         streamline ahead of the leading edges.",
