Development and validation of a CFD model for numerical simulation of a large natural draft wet cooling tower

摘要

Electricite de France (EDF) has commissioned the development of a CFD model, based on ANSYS Fluent v.16, which includes the specific equations (Poppe and Merkel) describing the physical phenomena occurring in a natural draft wet cooling tower (NDWCT). Heat and mass transfers between water and air, as well as drag equations for the two-phase system, are computed in specific zones such as the cooling fill, spray and rain zones.
