The paper is concerned with the experimentally known phenomenon that the detonation velocity of a tubular charge may markedly exceed that of a homogeneous charge of the same explosive. It is shown ...

This paper is concerned with detonation-propelled shocks (precursors) occurring in gas-permeable charges. It is shown that the basic aspects of the event may successfully be reproduced within a one-dimensional two-phase picture widely employed in the

This study is motivated by the observation that in combustion of hydrogen–oxygen/air and ethylene–oxygen mixtures the global activation energy appears to be high at low enough temperatures and low at high enough temperatures, reflecting the compl

The paper is concerned with the channel effect: detonation-propelled shocks occurring in tubular charges. It is shown that some salient aspects of the phenomenon may be successfully reproduced within a simple one-dimensional model assuming the gas–

The article is concerned with the experimentally known phenomenon of the precursor shock driven by the detonation of a tubular charge. It is shown that the basic aspects of the effect may be successfully captured within a one-dimensional two-phase ve

The effects of hydraulic resistance on the burning of confined/obstacle-laden gaseous and gas-permeable solid explosives are discussed on the basis of recent research. Hydraulic resistance is found to induce a new powerful mechanism for the reaction

Combustion and Flame. 158:42-47
The piston–flow interaction induced by a piston pushing hydraulically resisted gas through a long tube is discussed. It is shown that the hydraulic resistance causes a significant precompression and preheating of the gas adjacent to the piston’s

The experimentally known phenomenon of oscillatory instability in convective burning of porous explosives is discussed. A simple phenomenological model accounting for the ejection of unburned particles from the consolidated charge is formulated and a

The classical problem of fingering instability in miscible displacement is revisited. The finger-forming dynamics is considered as a multiple-scale process involving a thin inter-diffusion layer and large-scale background flow affected by the viscosi

Following the classical Buckley–Leverett theory for the two-phase immiscible flows in porous media a non-linear evolution equation for the water-oil displacement front is formulated and studied numerically. The numerical simulations yield a physica
