Complex Shapes and Dynamics of Dissolving Drops of Dichloromethane

Generation of cohesive motion was observed during the dissolution of mm‐sized drops of dicholoromethane into aqueous surfactant solutions. This system shows pulsating drops, multi‐armed rotors, and polygonal shapes. The sharp tips of these patterns eject much smaller droplets to form expanding halos...

Description
Summary:Generation of cohesive motion was observed during the dissolution of mm‐sized drops of dicholoromethane into aqueous surfactant solutions. This system shows pulsating drops, multi‐armed rotors, and polygonal shapes. The sharp tips of these patterns eject much smaller droplets to form expanding halos or swirling chains. The daughter droplets also undergo cascades of secondary and higher‐order splitting events.
