Dust explosions in connected vessels: Mathematical modelling

This paper is devoted to the topic of dust explosions in connected vessels, a research topic that has gained a lot of interest in recent years, not only because of its safety applications in processing units, but also because of the growth of mathematical models and computer simulations of such phenomena. The Eulerian–Eulerian approach has been used for modelling the propagation of explosions from one vessel to another via a duct. Different cases have been considered, where the size of the particles and the height of the duct have been varied. It is shown that the moment at which an explosion can occur is a function of the duct height: for bigger channels an explosion is more likely to occur in the second vessel. Similar results have been reported in literature on basis of experiments.
