Abstract
A computational study of explosion in air is presented. The governing equations13; used for two-component flow are those derived by Saurel and Gallouet by13; applying Drew's averaging procedure. The fluid composition in any cell is13; described in terms of the volume fraction of the components. This leads to a 5-13; equation model which has been solved in this work to compute the complex flow13; ensuing in the aftermath of a spherical blast. The components and the mixture13; are assumed to follow different gamma laws. The space terms are discretised by13; Rusanov upwind flux scheme. High quality results have been obtained for13; computations involving single as well as two-species involved in the explosion.
