Steady detonation problem for slow and fast chemical reactions

چکیده
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). After the analysis of the hyperbolic nature of the hydrodynamic equations, we formulate and solve the problem of the stationary propagation of a detonation wave. The differences of the shock structure in the two cases are shown by the presented numerical results.

Linear Stability of a Detonation Wave with a Model Three-Step Chain-Branching Reaction
The linear stability of a planar detonation wave with a three-step chain-branching reaction is studied by a normal mode approsch. The reaction model consists of a chain-initiation step and a chain-branching step governed by Arrhenius kinetics, with a chain-termination step which is independent of temperature. It mimics the essential reaction dynamics of a real chain-branching chemical system. T...
متن کاملDirect Simulation of Ultrafast Detonations in Mixtures
For nearly a century experimental measurements of the velocities of detonations in gases have been found in general agreement with those of the Chapman-Jouguet (C-J) hypothesis predicting velocities, relative to the burned gases, equal to the speed of sound in the burned gases. This was further supported by the Zeldovich von Neumann Döring (ZND) theories predicting Chapman-Jouguet velocities fo...
متن کاملDetonation wave solutions and linear stability in a four component gas with bimolecular chemical reaction
We consider a four component gas undergoing a bimolecular chemical reaction of type A1 + A2 A3 + A4, described by the Boltzmann equation (BE) for chemically reactive mixtures. We adopt hard-spheres elastic cross sections and modified line-of-centers reactive cross sections depending on both the activation energy and geometry of the reactive collisions. Then we consider the hydrodynamic limit sp...
متن کاملAnalytic and computational studies on micro-propulsion and micro-detonics
Based on a general theory of detonation waves with an embedded sonic locus that we have previously developed, we carry out asymptotic analysis of weakly curved slowly varying detonation waves and show that the theory predicts the phenomenon of detonation ignition and failure. The analysis is not restricted to near ChapmanJouguet detonation speeds and is capable of predicting quasi-steady, norma...
متن کاملNumerical 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...
