Evaporation of binary mixture nanofluid drops: Pattern formation

Abstract : The deposition patterns and internal flows inside drying binary nanofluid drops on heated substrates have been investigated. The evaporation of a binary mixture causes local concentration gradients at the air-liquid interface, resulting in a Marangoni flow. A temperature-dependant Marangoni flow has also been found, which has a crucial role in the final form of the dried deposits. The influence of substrate temperatures on the pattern formation has also been studied.
