Compressibility and vibrational-excitation effects in hypersonic shock-turbulence interaction

The interaction of turbulence with shock waves significantly modulates the frequency and amplitude of hydrodynamic fluctuations encountered by aerospace vehicles in low-altitude hypersonic flight. In these high-speed flows, intrinsic compressibility …

Combustion Toolbox: An open-source thermochemical code for gas- and condensed-phase problems involving chemical equilibrium

The Combustion Toolbox (CT) is a newly developed open-source thermochemical code designed to solve problems involving chemical equilibrium for both gas- and condensed-phase species. The kernel of the code is based on the theoretical framework set …

Combustion Toolbox v1.1.0 Development Update

I’m excited to announce that the next big update of our Combustion Toolbox, version 1.1.0, is coming soon! One of the most significant changes in this next version is that the code will adopt the Object-Oriented Programming (OOP) paradigm, replacing the previously used procedural software architecture.
