Abstract

An extended validation of the new Lagrangian particle model MicroSpray version for dense gas simulation is proposed.
MicroSpray simulates the dense gas dispersion in situations characterized by the presence of buildings, other obstacles, complex
terrain, and possible occurrence of low wind speed conditions. Its performances are compared to a chlorine railway accident
(Macdona), to a field experiment (Kit Fox) and to an atmospheric CFD model.

Keywords
