Liquid-infused surfaces (LISs) are composite solid–liquid with remarkable features such as liquid repellency, self-healing, and the suppression of fouling. This review focuses on fluid mechanics LISs, that is, interaction a flow field behavior drops surfaces. LISs can be characterized by an effective slip length is closely related to their drag reduction property, which makes them suitable for ...

The interaction between bubbles and solid surfaces is central to a broad range of industrial and biological processes. Various experimental techniques have been developed to measure the interactions of bubbles approaching solids in a liquid. A main challenge is to accurately and reliably control the relative motion over a wide range of hydrodynamic conditions and at the same time to determine t...

concerns about nitrate pollution in groundwater and downstream systems cause development of surface water management system to reduce losses of agricultural drainage water nitrate in subsurface drainage using subsurface irrigation from existing drainage lines, drainage water during the growing season and out of season is controlled. the overall objective of this study was to evaluate the effect...

Bubble Stability An acoustically levitated bubble can gain permanent stability due to the suppression of drainage by sound field and prevention capillary waves via liquid compensation. The everlasting shows a significantly enhanced particle adsorption ability, which shed light on development novel air-purification techniques without consuming any solid filters. More details be found in article ...

A method has been developed to infer the wettability of steam-water-rock systems based on the relationship between permeability and capillary pressure by Purcell. The Purcell model was extended to two-phase flow to verify whether the wettability is a function of water saturation. The results calculated using the experimental data showed that the wettability index in the drainage process was gre...

In this work the model of droplets coalescence in liquid/liquid dispersions in flow through fibrous media is proposed. It is derived for the computation cell being a cubicoid that comprises a single mesh gap and equal volumes upstream and downstream, which size corresponds to a packing factor of the filter media. The numerical approach takes into account deposition of droplets on the fibres as ...

This paper presents the development and assessment of two types of Long Period Fiber Grating (LPFG)-based sensors including a mobile liquid level sensor and a reflective sensor for the measurement of liquid level and fluid-flow velocity. Shewhart control charts were used to assess the liquid level sensing capacity and reliability of the mobile CO(2)-laser engraved LPFG sensor. There were ten gr...

A 44-year-old man presenting to our hospital emergency room with abdominal pain was hospitalized for hyperlipidemic acute pancreatitis. A pig-tail catheter was placed percutaneously to drain an abscess on day 22. Although the abscess improved gradually and good clinical progress was seen, pancreatic duct disruption was strongly suspected and endoscopic retrograde cholangiopancreatography was pe...

The liquid in foam forms an interconnected network, which is composed of Plateau borders, nodes, and films. One of the dominant pathways for foam drainage is flow through Plateau borders, and we use confocal microscopy to obtain experimental results for the flow fields inside individual Plateau borders. For three types of surfactants detailed comparisons are made with a model based upon the inf...
