Combining Advanced Turbulent Mixing and Combustion Models with Advanced Multi-Phase CFD Code to Simulate Detonation and Post-Detonation Bio-Agent Mixing and Destruction

Abstract

This work is focused on the development of computational models for the simulation of blast waves, heterogeneous combustion and their interaction with particle dispersion. In particular, a novel Eulerian-Lagrangian (EE/EL) hybrid approach is combines a hybrid Eulerian and Lagrangian framework for dense loading of particles. The Eulerian approach (EE) tracks particles in the dense regime however in the dilute regime the Lagrangian formulation becomes superior. Transition from dense to dilute is achieved by locally tracking the volume loading and at present, using a numerically determine transfer criteria. Verification and validation tests are conducted using canonical cases and compared to analytical and/or data as available. Good agreement is demonstrated, although further studies are still warranted.
