Shock waves

Theory of turbulence augmentation across hypersonic shock waves

Oral presentation in the 74th Annual Meeting of the American Physical Society’s Division of Fluid Dynamics

Combustion Toolbox is now available for testing

In the poster presented at the XI Mediterranean Combustion Symposium we introduced our first steps toward the development of an open-source wider-scope thermochemical tool. It’s been a while since then and we’re excited to say that Combustion-Toolbox (CT) is now available for testing.

Combustion Toolbox: A MATLAB-GUI based open-source tool for solving gaseous combustion problems

In this work, we present the development of a new thermochemical code (hereafter Combustion Toolbox, CT) that can be applied to gaseous combustion problems, even with condensed species. The kernel of the code is based in NASA’s Chemical Equilibrium …

Thermochemical effects of gas dissociation and vibrational excitation on hypersonic shock waves interacting with weak turbulence

The interaction between a weakly turbulent free stream and a hypersonic shock wave is investigated theoretically by using linear interaction analysis (LIA). The formulation is developed in the limit in which the thickness of the thermochemical …

Effect of equivalence ratio fluctuations on planar detonation discontinuities

We propose a linear asymptotic theory to describe the propagation of planar detonation fronts through heterogeneous mixtures of reactive gases consisting of random fluctuations in the fuel mass fraction. The analysis starts with the derivation of the …
