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 …
The interaction between turbulence and shock waves significantly modulates the frequency and amplitude of hydrodynamic fluctuations experienced by aerospace vehicles during low-altitude hypersonic flight. In these high-speed flows, intrinsic …
This release improves robustness and consistency in shock jump-derivative computations, generalizes the shock–turbulence interaction workflow for broader parametric studies, and integrates SHOCKTURBULENCE problems into the Combustion Toolbox App. It also includes bug fixes in chemical system updates, equilibrium stability improvements at low temperatures, and several minor usability enhancements.
We are pleased to announce that the first peer-reviewed article describing the Combustion Toolbox framework has been published as open access in Computer Physics Communications.

This release introduces new capabilities, plasma diagnostics, updated database (Burcat, January 2023), bug fixes, and performance improvements across the Combustion Toolbox framework.
1. New JumpConditionsSolver class for calculation of dimensionless Rankine–Hugoniot slopes A dedicated solver class has been implemented to compute thermochemical Rankine–Hugoniot jump conditions and the dimensionless RH slopes required in shock-turbulence interaction linear analysis ( Cuadra2024b, Cuadra2025a).
Combustion Toolbox v1.2.0 is now available! This release introduces a new turbulence module, a refactored equation-of-state system, significant performance improvements, and multiple usability enhancements across the entire ecosystem.
New Features and Enhancements 1.
Hypersonic flight involves a variety of complex flow phenomena that directly impact the aerothermodynamic loading of high-speed vehicles. The turbulence encountered during a typical flight trajectory influences and interacts with the shock waves on …
