N2 - The process of bubble growth inside an intensively evaporating sessile liquid drop on a heated structured black silicon has been studied. Experiments are carried out with volatile fluids FC-72, HFE 7100, ethanol, and water. The schlieren-based method was developed for investigations of the bubble growth inside a liquid droplet. The contact line velocity was measured during the droplet evaporation, including the case of a growing bubble inside the drop. The velocities of the contact line for droplet evaporation with/without bubble were compared. The contact line instability was detected emerging also due to the developed substrate structure. This can lead to an increase of local flows in the microregion and to significant heat transfer enhancement.
