A numerical simulation of the interaction between two real Pressurized Water Reactor containment sprays is performed with a new model implemented into the Eulerian CFD code NEPTUNE_CFD. The water droplet polydispersion in size has been treated with a sectional approach. The influence of collisions between droplets is taken into account with a statistical approach based on the various outcomes of binary collision. Experiments were performed on a new facility, and data obtained are compared with this two-fluid simulation. The results show a good agreement.
