Shock Waves and Turbulence - Physical Modeling, Numerical Challenges
Explore the complex world of shock waves and turbulence in this comprehensive lecture by Krishnendu Sinha. Delve into physical modeling, numerical challenges, and practical applications of shock-turbulence interactions. Learn about direct numerical simulation (DNS) and linear interaction analysis (LIA) techniques used to investigate turbulence amplification and enhanced heat transfer at shock waves. Discover the importance of unsteady shock oscillations in post-shock predictions. Examine various applications in supersonic and hypersonic shock-boundary layer interactions, aerospace vehicles, astrophysics, and nuclear engineering. Gain insights into canonical shock-turbulence interaction, turbulence kinetic energy, enstrophy amplification, and post-shock thermodynamic fields. Understand theoretical analyses, including the baroclinic effect on vorticity and propagating and decaying regimes. Explore modeling and simulation techniques for turbulent heat transfer, including new models that show significant improvements in predicting high heat transfer at shock impingement. Read more
