This paper examines the use of computational fluid dynamics as a tool for predicting human exposure to aerosols generated during compressed air spray painting in cross - flow ventilated booths. Wind tunnel experiments employing a mannequin and non - volatile oil provide data to evaluate the numerical predictions. Fidap (v8.01) is used to calculate the velocity field and particle trajectories, while in - house codes were developed to post - process the trajectory data into mass concentrations, size distributions, transfer efficiency, and over - spray generation rates. The predicted dimensionless breathing-zone concentration of 0.13 ± 23 percent is in agreement with the measured value of 0.13 ± 15 percent given the uncertainties involved in such comparisons. Computational fluid dynamics is a powerful tool capable of providing useful information to occupational hygiene engineers involved in controlling human exposures to toxic airborne contaminants.
