 note = {Two-dimensional hypersonic flows of the order of Mach number 25 are numerically solved for a blunt-body configuration using the Euler equations. The utilized numerical fluid dynamics technique is the BeamWarming finite difference one, where a bow shock wave in front of the blunt body is successfully captured in terms of several grid points, along with a mixed flow shock layer consisting of supersonic and subsonic regions separated by a sonic line. Starting from a simple set of chemical reactions involved in the dissociation and ionization of oxygen and nitrogen molecules, the numerical analysis proceeded to a fairly complicated reaction system where a total of 17 reactions and 11 chemical species are included. The results show that the Beam-Warming technique gives convergence to extremely fast hypersonic steady flow problems, even if there are complicated chemical reactions that might cause serious stiffness difficulties. However, even the present less stiff flow fields suffered consistent oscillations in the process of convergence to steady solutions. The difficulties were controlled by adjusting the secondorder and fourth-order artificial viscosities and the local time step. The acquired shapes of a bow shock wave and a sonic line showed good agreements with existing theories and experimental results.},
