Theoretical and experimental study on evaporation model for two-component liquid

Toxic vapor evaporated from released toxic liquid can cause people poisoning and environmental pollution. It is important for predicting toxic vapor concentration in air to forecast evaporation rate of toxic liquid. Especially for multi-component liquid, the evaporation process is complex, and evaporation rate is predicted by experimental model or semi-experimental model. And the influence of thermal transitivity is hardly considered. The model of predicting evaporation mass and temperature of two-component liquid was developed. The wind tunnel experiment device was designed. The solution composed of benzene and ethanol, which at different volume ratio, was placed in wind tunnel to make experiments. The measured value was compared with the predicted value. The result indicates that the predicted evaporation mass and temperature of solution are equivalent to the measured ones, and the average error is 25.82% and 33.79% respectively, thus providing the basis to research evaporation process of multi-component liquid.
