Abstract

A model for predicting evaporation and temperature
changes in water drops traveling through air was
developed and evaluated with laboratory data. The
model uses combined sensible heat transfer and diffusion
theory in an energy balance to simultaneously calculate
evaporation as droplet temperature approaches wet bulb
temperature of the air. Predicted droplet temperatures
agreed closely with measured temperatures. The
evaporation portion of the model was evaluated by
measuring loss of water over longer time periods after the
droplet reached wet bulb temperature. A volumetric
method using microliter syringes was used to measure
evaporation loss from 0.5 to 2 mm diameter drops.
Model predictions generally agreed with measured rates.
