N2 - Interaction of a cloud of inert and/or reactive particles with cellular detonation structures in stoichiometric ethylene-oxygen mixtures diluted with argon is simulated and studied. The analysis is done in both two and three dimensions, and both dilute and dense regimes of two phase flows are examined. The initial solid phase volume fraction and the length of the cloud are varied, and the effect on the detonation velocity and the detonation front are investigated. The effect of continuous particle injection into the detonation is analyzed. As the initial particle volume fraction and particle cloud length is increased the detonation suppression is increased. The variations in the reactivity of the reactive particle clouds in two and three dimensions are similar. The average gas phase volume fraction increases initially due to compression by the detonation front and decreases later due to dispersion. The effect of the detonation structures and the detonation front on the dispersion of particle clouds downstream of the front is analyzed. The average volume fraction is effected due to differences in particle dispersion between two and three dimensional cases.
