AbstractNumerical tools are used to design cooling towers or to evaluate the impact of systems modifications through retrofitting or degradation. However, due to the complexity of the physical phenomena involved and the dimensions of the systems, numerical modelling of draft cooling towers in three dimensions represents a significant challenge. This paper presents the work currently under way to implement a new cooling tower module in version 5.0 of the general, 3D CFD open source solver, Code_Saturne. To obtain significant accuracy and yet limit the number of flow equations which must be solved, the multiphase flow has been cast into the flow of liquid water and humid air using the drift flux model. The model and preliminary verifications on a realistic 2D tower case are presented. Extensions of the framework and validation against experimental data are then discussed.
