This talk discusses a stabilized finite element formulation for predicting high-speed compressible flows developed by CFSMgroup at the University of Calgary. The main focus is on non-ionized hypersonic flows in thermal non-equilibrium using two- and three-temperature models. The framework solves Navier-Stokes equations and energy conservation equations for compressible reacting flows in pressure-primitive variables, augmented with a residual-based discontinuity capturing operator. The weak imposition of the Dirichlet boundary condition is also discussed. The formulation is validated on multiple benchmark cases, including but not limited to a nitrogen reactor case, a 2D cylinder case at Mach 17, Mach 14 compression corner, 3D Mars Pathfinder re-entry vehicle at Mach 14, 3D axisymmetric hollow cylinder extended flare and double cone, and more. The accuracy of the numerical results is evaluated against available experimental and existed numerical tools. Preliminary results for modeling the HyMETS experiment are also presented.
Dr. Artem Korobenko is an Associate Professor in the Department of Mechanical and Manufacturing Engineering at the University of Calgary where he leads the Computational Fluids and Structural Mechanics Group (CFSMgroup). His research focuses on the development of high-fidelity multidisciplinary methods for the analysis and design of complex systems in aerospace, wind and marine engineering using large-scale computing. He actively collaborates with industries, governmental agencies, and academic institutions worldwide.
Dr. Korobenko is a recipient of the Fulbright Scholarship and most recently Alexander von Humboldt Fellowship for Experienced Researchers. He is a founding member and vice-president of the Canadian Association for Computational Science and Engineering and Member-at-Large of the USACM TTA on Computational Fluid Dynamics and Fluid-Structure Interaction. He is also a founding member and co-director of the University of Calgary Aerospace Network and the main organizer and the conference chair for the 16th World Congress on Computational Mechanics which will be held in 2024 in Vancouver, Canada.
