## Main features
The Combustion Toolbox is a MATLAB-based thermochemical framework designed to solve problems involving chemical equilibrium for both gas- and condensed-phase species. The toolbox is composed of several modules, each of which is designed to solve a specific class of problems:
- **CT-EQUIL** computes the thermochemical equilibrium composition of multi-component gas mixtures for prescribed set of chemical species (gaseous—including ions—or condensed phases) and thermodynamic constraints (e.g. pressure-enthalpy).
- **CT-SD** solves steady-state shock and detonation wave problems for both normal and oblique incidence.
- **CT-ROCKET** estimates the theoretical performance of rocket engines under highly idealized conditions.
- **CT-LIA** predicts shock-turbulence interaction statistics using linear theory, accounting for thermochemical effects.
- **CT-TURBULENCE** performs spectral and statistical analysis of turbulent flows, including energy spectra, Helmholtz decomposition, and turbulence diagnostics.
The framework also includes an intuitive **graphical user interface (GUI)**, with a **royalty-free standalone version** available for Windows, macOS, and Linux.
