Improved wood–kirkwood detonation chemical kinetics

Numerical Study of Blast Initiation of Detonation Using a Two Step Chemical Kinetics Model

The effect of chemical reactions on the blast initiation of detonation in gaseous media has been investigated in this paper. Analytical method is based on the numerical solution of onedimensional reactive Euler equations. So far, analyses on the blast initiation of detonation have modeled the combustion process as a one-step chemical reaction, which follows the Arrhenius rate law. Previous stud...

Steady detonation problem for slow and fast chemical reactions

Two sets of hydrodynamic equations for a mixture of four gases undergoing a bimolecular chemical reaction are discussed. The former consists in a system of balance laws for the case of a chemical relaxation time of the same order of the macroscopic processes (slow reaction). Conversely, the latter is a system of conservation laws for the case of short chemical relaxation time (fast reaction). A...

Detailed and Simplified Chemical Reaction Mechanisms for Detonation Simulation

We examine the chemical basis for simplified chemical reaction models by using numerical simulations of adiabatic explosion with detailed chemical kinetic mechanisms under pressure and temperature conditions relevant to detonations. We have studied hydrogen, methane, and ethane to determine the reaction structure and characterize it in terms of three overall features: induction time, energy rel...
