MULTI-PHYSICS METHODOLOGY FOR PHASE CHANGE DUE TO RAPIDLY DEPRESSURISED TWO-PHASE FLOWS

Objective

A multi-physics methodology is proposed to couple CFD calculations with models for phase change of rapidly depressurised mist of a fire suppression system. The methodology combines existing models with newly developed ideas with considers the coupling between large and small scales. The new models aim to describe the penetration of a two-phase flow and phase transitions into the confounding space and will be implemented as a user defined function in a tool chain and coupled with the nearfield CFD calculation. Both, a Lagragian and a Eulerian formulation will be followed using existing commercial tools and “in-house” multiphase solvers. Finally, one experiment is proposed to validate the numerical results in one relevant case.
