Numerical simulation of evaporation of volatile liquids

• The results of the validation of the developed pool evaporation model are presented.
• A sensitivity analysis is conducted to determine the effect of pool sizes on evaporation of a volatile liquid (hexane).
• The importance of the pool sizes effect decreases as the air velocity increases.

The paper presents the results of the validation of the developed pool evaporation model using literature and our own experimental data. The proposed model was used to examine the effect of wind velocity and pool sizes on the evaporation rate of volatile liquid (hexane). Contrary to the semi-empirical evaporation model widely used in hazard assessment, stronger dependence of evaporation rate on pool size at low wind speeds is obtained.
