Modelling spray vaporization for evaporative cooling of buildings

This article presents a one-dimensional model of spray vaporization that can be easily used in thermal performance simulations of buildings. A mathematical model of momentum, heat and mass transfer in the atomization zone was developed. Using a discrete particles model with separate flows and solving a non-homogeneous ordinary differential equations system, it is possible to verify the outflow, temperature and humidity of the treated air, at the end of the plume. These algorithms could be coupled to a building simulation code.
