Reliable computational prediction and modeling of high-enthalpy, hypersonic flows for certain aerospace applications are challenging due to coupling of multiphysics phenomena. The goal is to address some of the major gaps in existing hypersonic flow solvers, specifically the coupling of thermochemical nonequilibrium processes and turbulence. The primary issues considered with this coupling are the reliability of predictions over realistic geometries and the computational costs for its role in the design cycle. We extend the capability for aero-optical applications that is currently lacking in the existing hypersonic flow solvers. The authors are currently developing a computational tool for analysis of laminar and turbulent hypersonic external flow fields in non-equilibrium for a desired fidelity (high/low) using criteria driven by considerations of computational efficiency and accuracy of prediction, often provided by the design team. The paper describes the main features of the code, viz. numerical schemes (such as high-order accurate schemes), physical models (such as libraries for state-to-state kinetics solving master equation, lumped vibrational relaxation models and transport coefficients) and pre/post-processing modules. Validation tests and illustrative examples are presented to show its current state in the development.
