The present work deals with a model of flame propagation through hydrocarbon-air mixtures in packed beds and the dependence of flammability limits for on the system geometry. Particularly, the one-dimensional effects of buoyancy are investigated with respect to their influence on the experimentally found differences between upward and downward flammability limits. To this aim, an efficient solution procedure is constructed and implemented for this complex transient model, taking the form of an initial and boundary value problem of a set of partial differential equations.

Abstract
The present work deals with a model of flame propagation through hydrocarbon-air mixtures in packed beds and the dependence of flammability limits for on the system geometry. Particularly, the one-dimensional effects of buoyancy are investigated with respect to their influence on the experimentally found differences between upward and downward flammability limits. To this aim, an efficient solution procedure is constructed and implemented for this complex transient model, taking the form of an initial and boundary value problem of a set of partial differential equations.File in questo prodotto:
