The real time movements of Butanol and Isopropyl alcohol (IPA) on a slide glass (VIDEO)
Caption
Flow pattern of two volatile liquids butanol (left) and isopropyl alcohol (right) on a glass slide near the three-phase contact line: the surface, liquid, and air. The movement can be visualized by tracer particles where the tracing tracks of fluorescent particles are overlap of 100 continuous frames. While both liquids are volatile their dynamics of movement can vary significantly. While capillary action moves the droplet across the surface, in the case of IPA the Marangoni effect causes the liquid to stagnate. Researchers utilized these findings to expand on the current understanding of the fluid dynamics of liquid.
