MS053 - Advances In Modelling and Simulation for High-Speed Aerodynamics
Keywords: Computational Fluid Dynamics. Computational Fluid Dynamics, High-Fidelity Modelling, Rarefied Gas Dynamics, Supersonic/Hypersonic Aerodynamics
Recent years have witnessed a renewed interest in developing high-speed flight technology . For instance, commercial aircraft manufacturers are heavily investing in hypersonic technology that can dramatically reduce intercontinental passenger flight time making same-day global round trips a reality. The wide range of atmospheric and flow conditions corresponding to different altitudes and Mach numbers that a hypersonic vehicle undergoes presents a huge challenge to aerodynamic design, propulsion, and flow control. At lower altitudes, where the flow is regarded as continuum, the effect of turbulence is critical, whereas at higher altitudes, flow rarefaction due to low-density effects becomes important. This warrants high-fidelity numerical models that can reliably simulate these conditions, at all altitudes, accurately. This mini-symposium will target and communicate on recent progress in CFD for supersonic and hypersonic aerodynamics at all altitudes. Topics of interest of this mini-symposium include, but are not limited to: - High-performance computing of high-speed flows - Numerical schemes, models, and algorithms - Supersonic/hypersonic wall bounded flow and boundary layer control. - Shock-wave/boundary layer interaction - Turbulence modelling for high-speed flows - Fluidâ€“structure interaction in high-speed flows - Application of CFD to supersonic/hypersonic engineering - Direct simulation Monte Carlo (DSMC) and hybrid CFD-DSMC models for high-altitude flows - Alternate models like Method of Moments, gas kinetics - High temperature effects related to chemistry, ablation, etc.
