Numerical analysis on process of particurates dispersion by explosion(*in Japanese)
Hiroaki Miura and Masaki Takeda


The dispersion processes of particles such as CBRNE (Chemical, Biological, Radiological, Nuclear and Explosives) materials blown by the explosion on the ground are simulated using the compressible fluid dynamics simulation code. These simulations provide the initial condition of particles and gas flow properties for the incompressible fluid dynamics simulation to predict the long term dispersion process of the particles. The effect of the side walls on the particles dispersion process is estimated in the simulations of explosion inside the building with simplified wall.
