A Study of Annular Slurry Jet for Abrasive Waterjet Cutting

Fluid-flow-driven particle migration through porous networks reflects the interplay between various particle-level forces, the relative size between migrating particles and pore constrictions, and the spatial variability of the velocity field. Experimental evidence shows that particle migration in radial fluid flow results in selfstabilizing annular clogging patterns when the particle size appr...

This paper is Part II of a two-part study devoted to measurement and prediction of the saturated flow boiling heat transfer coefficient in water-cooled micro-channel heat sinks. Part I discussed the experimental findings from the study, and identified unique aspects of flow boiling in micro-channels such as abrupt transition to the annular flow regime near the point of zero thermodynamic equili...

abstract annular pancreas (ap) is a rare congenital malformation resulting from failure of pancreas ventral anlage rotation with the duodenum. this leads to a ring of pancreatic tissue that envelops the duodenum. clinical manifestations of ap most commonly develop in infancy or early childhood but can present at any age. the diagnosis of ap, usually suggested by an upper gi series or abdominal ...

An in-line oil-water separator has been designed and is investigated for singleand two-phase flow. Numerical single-phase flow results show an annular reversed flow region. This flow pattern agrees qualitatively with results from measurements. In the two-phase flow simulations two different drag laws have been used to model the interaction between the phases. The velocity field of the singleand...
