Performance Analysis of Natural Draft Cooling Tower

A CFD model of a NDWCT has been developed with FLUENT 12. The geometry and design parameters have been based on those of the reference tower. This model is an advance on previous models, with the generality of the empirical correlations used and the detail to which condensation is represented, improved over previous efforts. The water flow in the rain and spray zones has been modeled in more detail with two-dimensional Lagrangian particle motion and the droplet distribution in the rain zone is also represented.
