Theory of turbulence augmentation across hypersonic shock waves in air

The interaction between a weakly turbulent free stream of air and a hypersonic shock wave is investigated theoretically by using linear interaction analysis (LIA). The perturbation-free jump conditions across the shock are computed using Combustion …

Theory of turbulence augmentation across hypersonic shock waves

The interaction between a weakly turbulent free stream and a hypersonic shock wave is investigated theoretically by using linear interaction analysis (LIA). Modified Rankine-Hugoniot jump conditions that account for dissociation and vibrational …

Development of an open-source thermochemical code: Fundamentals and application to shock turbulence interaction problems in the hypersonic regime

In this seminar, we present the development of an in-house thermochemical code (hereafter Combustion-Toolbox) that can be applied to gaseous combustion problems. The code stems from the minimization of the Gibbs–Helmholtz free energy by using …
