An analytical model predicting the evaporation rate for multi-component liquid drops is proposed, taking into account the effect of all mass diffusivities within the gas phase. The increment of the evaporation rate due to gas convection is included according to the film theory. The model is validated against experimental measurements for bi and tri-component motionless drops. A simpler model, based on the single-component analogy, is also proposed and compared to other simplified models from the open literature, with good agreement.

Abstract
An analytical model predicting the evaporation rate for multi-component liquid drops is proposed, taking into account the effect of all mass diffusivities within the gas phase. The increment of the evaporation rate due to gas convection is included according to the film theory. The model is validated against experimental measurements for bi and tri-component motionless drops. A simpler model, based on the single-component analogy, is also proposed and compared to other simplified models from the open literature, with good agreement.File | Dimensione del file | Formato | |
