The flow field induced by spherical blast waves propagating into perfect and imperfect dusty gases

Research output: Contribution to journalArticlepeer-review

Abstract

The flow fields induced by spherical blast waves propagating into dusty gases are investigated numerically. In the case of a moderate blast wave the gaseous phase is assumed to be perfect, while for strong blast waves real-gas effects are accounted for. The effects of the dust loading ratio and the initial energy used to generate the blast on the suspension properties are investigated and discussed in detail. Owing to the fact that the physics involved inside the exploding charge is very complicated, the present solution is appropriate for simulating the flow induced by the blast wave outside the exploding sphere only.
