Unexpected Marangoni Condensation in Negative Binary Mixtures
Abenezer Abere, Patricia B. Weisensee
Marangoni condensation - where surface tension gradients induce instabilities that lead to condensate film breakup into discrete droplets - has traditionally been thought of being…
Droplet impact and Leidenfrost dynamics on a heated post
Junhui Li, Patricia Weisensee
This study experimentally explores fluid breakup and Leidenfrost dynamics for droplets impacting a heated millimetric post. Using high-speed optical and infrared imaging, we invest…
Marangoni-Induced Reversal of Meniscus-Climbing Microdroplets
Jianxing Sun, Patricia B. Weisensee
Small water droplets or particles located at an oil meniscus typically climb the meniscus due to unbalanced capillary forces. Here, we introduce a size-dependent reversal of this m…
Dynamic wetting and heat transfer during droplet impact on heated bi-phobic wettability-patterned surfaces
Wenliang Qi, Patricia B. Weisensee
This paper reports the dynamic wetting behavior and heat transfer characteristics for impinging droplets on heated bi-phobic surfaces (superhydrophobic matrix with hydrophobic spot…
Enhanced Water Nucleation and Growth Based on Microdroplet Mobility on Lubricant-Infused Surfaces
Jianxing Sun, Xinyu Jiang, Patricia B. Weisensee
Lubricant-infused surfaces (LISs) can promote stable dropwise condensation and improve heat transfer rates due to a low nucleation free-energy barrier and high droplet mobility. To…
Evaporation of sessile water droplets on horizontal and vertical bi-phobic patterned surfaces
Wenliang Qi, Junhui Li, Patricia B. Weisensee
This paper presents an experimental study on thermal transport to single water droplets evaporating on heated bi-phobic surfaces consisting of a superhydrophobic matrix with a circ…
Microdroplet self-propulsion during dropwise condensation on lubricant-infused surfaces
Jianxing Sun, Patricia Weisensee
Water vapor condensation is common in nature and widely used in industrial applications, including water harvesting, power generation, and desalination. As compared to traditional…
