Abstract: This paper is based on a research that attempted to observe the sensible cooling effect of evaporation of water from a linear waterway by measuring the microclimatic weather data of its proximity. The location in question was Phoenix, Arizona. Evaporation and prevalent site conditions were modeled using computational fluid dynamics (CFD) software, FLOVENT. The model was validated by comparing the predicted data with the measured data. It was found that the model did not successfully capture the sensible cooling effect indicated by the measured air temperature data. It is rare that CFD and experiment would match exactly. However, this paper discusses the building of this type of model and the finer nuances of modeling evaporation for the outdoors using the first principles.
