| Abstract: | Detonation in heterogeneous systems involving parallel layers of two different substances was investigated. It was assumed that the denser medium can undergo fast chemical reaction without mixing with the other medium, and the detonation propagates along the two layers. The process of initiation is associated with a shock wave advancing through the medium of lesser density. An idealized gasdynamic model of the phenomenon is proposed in order to evaluate detonation parameters of the two-layer system on the basis of the characteristic features of its constituents. As calculation shows, in the absence of mixing between the two layers, the detonation is capable of propagating at a higher velocity than in the case when the constituents forming the layers are mixed. |
