Nuclear reactor containment flows – modelling of stratified layer erosion by a wall-deflected jet

A number of international computational benchmarks were devoted to assessing the capability of commercial and in-house Computational Fluid Dynamics (CFD) codes to predict transient evolution of the concentration and velocity fields of the nuclear power plant containment atmosphere in the course of severe accidents. In these benchmarks the velocity and concentration fields were measured during the transient. Usually, a vertically directed jet …
