Abstract

Regular and irregular cellular detonation structures for stoichiometric ethylene-oxygen mixtures are simulated and studied. The structure of both two-dimensional (2D) and three-dimensional (3D) detonations are considered and simulated using a simplified chemical model with Arrhenius kinetics. The motion of the triple point lines on the detonation front and the occurrence of the "slapping waves", in case of 3D simulations, is presented. The effect of turbulence-detonation interaction on the detonation front and the presence of finer scales and the distortion of the structures produced by detonation due to turbulence are discussed. Further more, the mass fraction of the reactant downstream of the detonation front is analyzed. The enhancement of mixing and the formation of unreacted gas pockets downstream of the front due to turbulence is addressed in particular.
