Abstract Numerical simulation of continuously rotating detonations stoichiometric two-fuel mixture with air has been carried out for the cylindrical annular detonation chamber (DC) rocket-type engine. The syngas (1-α)СO+αH2, a binary hydrogen H 2 and carbon monoxide CO, is taken. We studied global flow structure in DC, detailed transverse wave (TW) front continuous regime. Integral characterist...

The present work is concerned with the development of a new algorithm for determination of the equilibrium composition of gaseous detonations. The elements balance equations, and the second law of thermodynamics (i.e., the minimization of the Gibbs free energy of products), are used to determine the equilibrium composition of the detonation products. To minimize the Gibbs free energy with tradi...

In this work, we explore the effect of initial density variation in combustible mixture on nonlinear dynamics one-dimensional gaseous detonation propagation. Studies dynamical behavior pulsating are frequently based upon reactive Euler simulations with one-step Arrhenius chemistry. regions control parameters space, i.e., activation energy Ea, 1-D shown to exhibit chaotic at values 28.5 and 30.0...
