FLUIDYN–PANACHE - ATMOSPHERIC AIR FLOW & POLLUTANTS DISPERSION
Fluidyn-PANACHE is a software family dedicated to the simulation of atmospheric pollutant dispersion and air quality prediction. Based entirely on a 3D-CFD approach (Computational Fluid Dynamics), the modeling tools can predict with high accuracy the gas/particle dispersion both in the near field and far field. Among all the features, Fluidyn-PANACHE takes into account the effects of buildings, complex topography, land covers, weather conditions, atmospheric boundary layer, transient and chronic emission (gas, particles, dense gas, fire products, 2 phases releases…).

FLUIDYN-PANEPR
fluidyn-PANEPR is the module of fluidyn-PANACHE dedicated to the 3D simulation of accidental dispersion from industrial sites. It analyzes the consequences of accidental dispersion of pollutant discharge in process industries due to rupture or leaks in pressurized or nonpressurized tanks, pipes, valves, joints etc. and combustion products due to fires. fluidyn-PANEPR is a powerful tool which can be used to plan anticipatory measures and solve problems in case of industrial accidents. It integrates the 3D modelling characteristics (wind, turbulence and pollutant transport) of fluidyn-PANACHE and takes into account the influence of topography, obstacles (in near field), and buildings, influence of vegetation and terrain on dispersion, solar radiation effects and ambient atmospheric conditions. It can simulate transient effects of the following physical phenomena: compressible flow, buoyancy effects, atmospheric release interactions, and variable source time.
