Abstract
The mechanism of the enhancement of a detonation wave in a two-phase reactive medium was numerically explored. The two-phase medium consisted of heptane droplets with radii 150 to 500 microns, dispersed in pure oxygen. All the considered concentrations were stoichiometric. A special algorithm was used in order to differentiate between the numerical and phenomenological oscillations. The oscillation of the main detonation wave was caused by a set of secondary waves, produced in the reaction zone behind the wave front. The wave length of the secondary waves was found by numerical methods. The graphical presentation of the process enables to obtain an overall picture of the mechanism of wave enhancement.
