Liquid-infused surfaces (LIS) are a promising technique for reducing friction, fouling and icing in both laminar turbulent flows. Previous work has demonstrated that these susceptible to shear-driven drainage. Here, we report different failure mode using direct numerical simulations of channel flow with liquid-infused longitudinal grooves. When the liquid-liquid surface tension is small and/or ...

Motivated by the goal of understanding how to most homogeneously fill the lungs with perfluorocarbon for liquid ventilation, we investigate the transport of liquid instilled into the lungs using an intact rabbit model. Perfluorocarbon is instilled into the trachea of the ventilated animal. Radiographic images of the perfluorocarbon distribution are obtained at a rate of 30 frames/s during the f...

This paper details results of an experimental study of the capture of solid and liquid aerosols on fibrous filters wetted with water. A microscopic cell containing a single fibre (made from a variety of materials) was observed via a microscope, with a high speed CCD camera used to dynamically image the interactions between liquid droplets, zeolite and PSL particles and fibres. Variable quantiti...

complication of laparoscopic cholecys− tectomy and is associated with significant morbidity and mortality when diagnosis is delayed [1± 3]. Endoscopic closure has not been reported, although it has be− come an alternative for selected patients with postoperative gastrointestinal fistu− las in other locations [4]. We report the case of a 59−year−old male who underwent endoscopic retrograde chola...

As known from thermodynamic principles, the surface tension of a liquid decreases with increasing temperature. This property can be used to force a liquid film to climb a vertical substrate whose lower end is held warmer than the top. The vertical gradient in surface tension generates a surface shear stress that causes the liquid film to spread upward spontaneously in the direction of higher su...
