Effects of Confinement on Combustion of TNT Explosion Products in Air

Description: Turbulent combustion fields established by detonative explosions of TNT in confinements of different sizes are studied by high-resolution numerical simulation, using AMR (Adaptive Mesh Refinement) method. The chambers are filled with nitrogen or air at NPT conditions. In the second case, the detonation products, rich in C and CO, act, upon turbulent mixing with air, as fuel in an exothermic process of combustion, manifested by a distinct pressure rise. It is the evolution in space and time of t… more

Multi-Fluid Model of Exothermic Fields in Explosions

Description: A Multi-fluid Model is proposed for turbulent combustion in explosions at infinitely-large Reynolds, Peclet & Damkoehler numbers. It is based on the gas dynamic conservation laws for the mixture, augmented mass-energy conservation laws for each fluid (fuel-F, oxidizer-A and products-P). Combustion is treated as material transformations in the Le Chatelier plane--rather than ''heat release'' found in traditional models. This allows one to construct thermodynamically-consistent representations of… more

Thermodynamics of Combustion in a Confined Explosion

Description: Considered here are explosions from condensed TNT charges--where the expanded detonation products gases are rich in C and CO [1]. Mixing with air causes oxidation/combustion [2], which dramatically increases the pressure in confined systems (vid. Fig. 1). We treat this as an Inverse Problem: infer fuel consumption from the measured pressure P {triple_bond} {bar p}(t)/p{sub i}. The Model expounded here represents a valuable tool for extracting the evolution of combustion system from a readily me… more
