2021年10月20日 where k is the Boltzmann constant [J/K], T is the absolute temperature [K], \(\mu\) is the dynamic viscosity [Pa \(\,s\)] and r is the particles radius [m]. For objects of approximately spherical shape (e.g. many types of molecules, colloids or bacteria) for which the radius is known, several methods have been developed in the past decades to

2020年7月8日 Liquid metallic films are the constituting elements of metallic foams and are governed by a complex interplay between the liquid—here aluminium alloys—, the film stabilising solid particles contained in the melt, and the gas phase. We use synchrotron X-ray radioscopy to study particle dynamics and analyse particle motions by applying novel

2015年4月1日 Chatterjee and Flury [9] used 3D printing to fabricate particles with various geometric shapes (cylinder, cone, sphere, tetrahedron) which they then passed through the interface whilst measuring the capillary forces on them. The particles used were roughly 5 mm in diameter and thus much larger than those traditionally studied at interfaces and in

2022年8月25日 The particle image velocimetry tests and the flow field simulation results revealed that the forming region of the liquid vortexes was consistent with the microparticle aggregation region. The control method proposed here has the merits of simple structures, no damage to the controlled objects and large control ranges.

2022年11月10日 Universal assembly of liquid metal particles in polymers enables elastic printed circuit board. By Wonbeom Lee, Hyunjun Kim, Inho Kang, et al. Gallium (Ga) is a silver-blue metal that melts at 29.8°C and is useful for creating alloys with a wide range of properties. For example, an alloy of Ga and indium (In) with roughly a 3-to-1 ratio has a ...

2013年11月26日 Common nematic oils, such as 5CB, experience planar anchoring at aqueous interfaces. When these oils are emulsified, this anchoring preference and the resulting topological constraints lead to the formation of droplets that exhibit one or two point defects within the nematic phase. Here, we explore the interactions of adsorbed particles

88287. Liquid-solid flow represents the flow of a liquid continuum carrying dispersed solid panicles suspended and conveyed by the drag and pressure forces of the liquid acting on the particles. The aim of those slurry flows may be the transport of bulk-solids or physical or chemical processes between carrier liquid and solids.

Abstract. We investigate the sedimentation of fine particles in liquid channels of foams. The study combines numerical simulations with experiments performed in foams and in isolated vertical foam channels. Results show that particulate motion is controlled by the confinement parameter ( λ) and the mobility of the channel surfaces modelled by ...
