Benchmark proposal for stratified horizontal two-phase flow phenomena

Two-phase flow in the primary circuit of a PWR:LOCA scenarios Relevant example of stratified two-phase flow regime for Computational Fluid Dynamics validation:

Slug flow regime characterized by:acceleration of the gaseous phase, transition of fast liquid slugs
Aims of the numerical simulations:
feasibility study of numerical prediction of slug flow with multiphase flow models built in a commercial code (ANSYS-CFX) to prove the understanding of the general fluid dynamic mechanism leading to slug flow
