Experimental Investigation of Neutrally Buoyant Immiscible Drop Dynamics in Collapsible Vessels
Volume 2: Multiphase Flows Applications; Fluids Applications; Microfluidics; Fluids Mechanics Fundamentals; Fluids Engineering EducationAbstract The transport dynamics of immiscible drops in large, thin-walled vessels are critical for understanding cardiovascular functions and medical procedures. These flexible vessels are prone to deformations, such as buckling or collapse, caused by pressure imbalances due to posture changes, fluid redistribution, or muscle ...

Abstract A drop-collapse method has been refined for use as both a qualitative assay to screen for surfactant-producing microbes, and as a quantitative assay to determine surfactant concentration. The assay is rapid, easy to perform, reproducible and requires little specialized equipment.

Abstract The bed collapse technique, firstly proposed by Rietema in 1967, is a standard technique used for the characterization of powders belonging to Geldart's Group A classification. When applying this technique to gas fluidization, a windbox gas deaeration rate needs to be considered carefully.

Ecological traits of reefs across the Permian-Triassic boundary interval coincide with a modeled decline of atmospheric oxygen throughout the Permian Period. Selective extinction and recovery patterns within the reef system are observed both at the end of the middle Permian (end-Guadalupian) and at the Permian-Triassic boundary.

Abstract A detailed geometric analysis is presented of stabilized clusters of strongly coagulated fluid drops in a liquid medium. These systems are characterized by a finite contact angle θ at the perimeter of each thin liquid film separating adjacent drops.

Ball lightning is modeled by the bulk of humid air heated to temperatures of 600–650 K and containing a multitude of charged drops and microbubbles of size 10−5 cm or less, as well as water vapor heated to a near-critical temperature. The condensation of the vapor in the microbubbles, followed by the cooling of resulting droplets, generates energy ...
