COMPUTATIONS OF THERMODYNAMIC PARAMETERS OF COMBUSTION PRODUCTS BEHIND OVERDRIVEN DETONATION WAVE

A detailed description of the computational model of thermodynamic parameters of the combustion products behind overdriven detonation wave is presented. The model is based on one-dimensional steady flow model with the negligence of body forces, without heat addition and without heat and momentum losses. The model calculates chemical and thermodynamic equilibrium state of the combustion products for the combustion of hydrogen or any hydrocarbon in oxygen. A detailed description of the iterative solution procedure of the model and computer program DEFAST executing this solution are given. Illustrative example of the overdriven detonation wave in stoichiometric hydrogen-oxygen mixture with the initial pressure 0.1 MPa and temperature 293 К is also presented.
