Numerical Simulation of the hydrodynamics of gas-liquid Flow in an Evaporative Cooler Based on Computational Fluid Dynamics

In this study the hydrodynamics of gas-liquid two-phase flow in the evaporative cooler is modeled using computational fluid dynamics tools. The two dimensional CFD model has utilized the standard k- ε turbulence model as the turbulence closure. The current simulation has adopted both the Eulerian approach for the air and water phases. The film nature of the water flow has been approximated by droplets flow with a given velocity. A good agreement between model and expected results based on macroscopic momentum balance is noticed.
