Finite Element Method-Based Stabilized Formulation for Hypersonic Flows in Thermal Non-Equilibrium

Artem Korobenko, Associate Professor & Associate Head for Research, University of Calgary

Abstract

The computational modeling of hypersonic flows in thermal non-equilibrium remains an active area of research. This talk presents the Streamline-Upwind Petrov–Galerkin (SUPG) framework with finite element discretization, aimed at predicting non-ionized hypersonic flows under thermal non-equilibrium conditions. The Navier-Stokes and energy conservation equations for compressible, reacting flows are solved using pressure-primitive variables, complemented by a residual-based shock capturing operator. Non-equilibrium effects are captured using a two-temperature model (vibrational non-equilibrium). The framework's capabilities are demonstrated through various 2D and 3D benchmark cases, with validation provided by comparison to existing numerical and experimental data in the literature.
