This paper documents some preliminary activities associated with the extension of the HPCMP CREATE TM -AV Kestrel computational fluid dynamics software toward thermochemical generality. Components of the Kestrel software currently carry assumptions of a perfect gas. Facilities modeling needs at Arnold Engineering Development Complex (AEDC) require thermochemical effects associated with higher temperatures, higher pressures, and chemical reactions. The initial focus of the effort is on meeting simulation needs for AEDC facilities. This effort is being coordinated with longer-term planning to meet needs of the broader Kestrel user base for simulations involving higher temperatures, chemical reactions, and mixing. Nomenclature SymbolMeaning a = speed of sound A = area A = flux Jacobian matrix C p = specific heat at constant pressure e = specific internal energy E = specific total internal energy F = flux vector h = specific enthalpy H = specific total enthalpy I = identity matrix k p = shock sensor M = Mach number p = static pressure Pr = Prandtl number r = recovery factor s = entropy T = static temperature t = time u, v, w = Cartesian velocity components U = vector of conserved variables V = velocity V -= volume x, y, z = Cartesian position components y s = mass fraction of species s β = shock switch γ = ratio of specific heats * Aerospace Testing Alliance,
