Short Abstract: The problem is concened with a rational interpretation of the thermodynamic and fluid dynamic phenomena taking place in a closed vessel upon detonation of an explosive charge and subsequent turbulent combustion of its products,acting as fuel for an exothermic reaction with the shock compressed air. The paper presents the chemical and thermodynamic background and its numerical results, deduced for this purpose from mass spectroscopic data and pressure records, acquired upon explosion of a 0.8 charge of TNT in a 17 m3 chamber filled with air. The evolution of the flow field will be presented by movies of its fluid dynamic phenomena, computed on this basis.
