AZF_2M

Case description

Real case of Alziare (AZF) pollutant dispersion incident. Uses PASPOL for Lagrangian particle dispersion modeling and nested domains to simulate tracer transport.

Configuration

Specificities

Scientific specificities - Pollutant dispersion simulation - Particle tracking with PASPOL - 2 release points

Technical specificities - 2-domain nesting (1:5 ratio) - Short simulation (1 hour)

Validation

• Tracer concentration measurements

• Dispersion patterns

Numerical ressources

1 node, 8 cores (MPI parallel)
