Abstract

Transient one-dimensional model of fluid dynamics based on the solution of multiphase flow is described. The model includes the provision for one fluid to be converted into another by a combustion' process. The results deriving from the present model are compared with those from our earlier work, using a multi-gas formulation of the conservation equations, for the problem of two different gases in a shock tube. Agreement is shown to be excellent if the two species have the same velocity and temperature. If this is not the case the two approaches can give very different results. The fundamental differences between the two models are discussed, concluding that the multiphase flow model is more appropriate for the study of steam explosions. The second part of the paper applies the multiphase flow model to the study of detonations.
