A three-dimensional CFD simulation of corium jet breakup in intensive vapor generation condition

A three-dimensional CFD simulation of corium jet breakup in intensive vapor generation condition

The complexity of ex-vessel phenomena during a severe accident limits the most previous CFD applications only to hydrodynamic aspects. The present study performs numerical analysis of jet breakup and debris bed formation under intensive steam generation using the STAR-CCM + code. The CFD prediction...
