Combustion Toolbox is a a MATLAB-GUI based tool for solving gaseous combustion problems.
Features
  • The code computes the equilibrium composition by minimization of the Gibbs–Helmholtz free energy by using Lagrange multipliers and allows gaseous and condensed species
  • The code also computes equilibrium properties of ideal plasmas, i.e., no coulombic interactions are considered
  • It employs NASA’s 9-coefficient polynomial fits to evaluate the thermodynamic properties
  • Results are in good agreement with, NASA’s Chemical Equilibrium with Applications (CEA) program, CANTERA and Caltech’s Shock and Detonation Toolbox
  • All the routines and computations are encapsulated in a more comprehensive and user-friendly GUI, which will be released in early November
  • The code is in it’s transition to Python
  • Display predefined plots (e.g., molar fraction vs equilence ratio)
  • Export results in a spreadsheet (requires Excel)
Chemical equilibrium problems
  • TP: Equilibrium composition at defined temperature and pressure
  • HP: Adiabatic temperature and composition at constant pressure
  • SP: Isentropic compression/expansion to a specified pressure
  • TV: Equilibrium composition at defined temperature and constant volume
  • EV: Adiabatic temperature and composition at constant volume
  • SV: Isentropic compression/expansion to a specified volume
Shock calculations
  • Pre-shock and post shock states
  • Equilibrium or frozen composition
  • Incident or reflected shocks
  • Chapman-Jouguet detonations and overdriven detonations
  • Hugoniot curves
  • Ideal jump conditions for a given adiabatic index and pre-shock Mach number
