A Computational Fluid Dynamics Analysis of an Indirect Evaporative Cooler Employing the Particle Transport Method Torsten Berning, Henrik Sørensen, Mads Pagh Nielsen



A numerical analysis of heat and mass transfer in an indirect evaporative cooling system for building applications is presented. The model is based on the computational fluid dynamics software CFX-4 and makes use of the built-in Spray Drier model to study the droplet movement, heat transfer, and evaporation rate from the water to the exhaust air. The effect of the average droplet size and mass flow rate as well as the angle of the heat exchanger on the cooling performance to the supply air is reported.
