Study of the dependence of hydrocarbon evaporation rate on saturated vapor pressure and airflow velocity
Abstract
The article investigates the evaporation rate of hydrocarbons (pentane, hexane, heptane, octane) at different air flow velocities. A comparison of experimental and calculated data revealed significant discrepancies. It was found that in the absence of airflow, the evaporation rate linearly depends on the saturated vapor pressure, while the influence of aerodynamic factors increases with airflow. The results can be used to improve methods for calculating the evaporation of flammable liquids. Formulas were derived for calculating the evaporation intensity at 0 m/s and for calculating the correction factor at air velocities up to 1 m/s.
