Abstract
The effect of turbulence on the evaporation of diethyl ether droplets is investigated by means of digital in-line holography. Lagrangian tracking of thousands of droplets evidences an increase of the mean evaporation rate related not only to the mean relative velocity viewed by the droplets but also to the fluctuations of this velocity.
