The condensation and evaporation of binary droplet have been theoretically and numerically investigated. The evaluation of the mole fractions at the droplet surface is based on the model, where a thin, well-stirred liquid film is allowed to mix with the droplet by diffusion. The evaporation of ammonia-water droplet is numerically predicted. The effect of small liquid phase diffusitivies seems to cause the surface composition to differ from the bulk. However, the effect on the evaporation rate is reduced due to coupling with the droplet temperature.
