Blast wave simulation for civil engineering

The best alternative to test fields to assess blast effects on structures is numerical simulation. The best numerical model is the one that enhance the ratio accuracy / cost, indeed, an accurate simulation is useless if it came at an excessive cost in views of time or needed resources. In this study, a coupled solution, that overlooks the blast wave formation, is presented and compare with full simulation and experimental results from a shock tube. In a first part, the different ways of finding the blast wave at a certain distance from and explosive charge are compare, in a second part, the suitable ones is use in 3D software that deals with fluid and structure.
