Hilgenfeldt, Sascha Liu, Banglin 2015-01-21T19:48:32Z 2015-01-21T19:48:32Z 2014-12 2015-01-21 Hsia, K. Jimmy 2014-12 We developed a robust simulation tool that provided energetic and geometric information of droplets deposited on patterned surfaces. Deformation of the droplet in response to discrete features in the contact plane was examined and quantified on an energy basis. Additionally, quasi-static simulation of relative movement between droplet and substrate was performed. Energy-displacement response of the droplet was found to exhibit surface tension-dominated elastic behavior. Experimental effort was carried out in combination with simulations. Using a novel technique, synchronized video and force response were obtained for droplets moving on patterned PDMS substrate. Features present in the force-displacement data were analyzed and linked to various aspects of the droplet-substrate system, including surface modes of the pinned droplet, residual liquids deposited behind the trailing edge, and geometric parameters of the substrate pattern.
