Flow patterns of ice slurry flows
WebTo analyse flows and to determine the flow patterns the investigation of velocity profiles can lead to valuable informations. For example, they can be on the rheological nature of the fluid or on the type of flow (laminar, transitional or turbulent flow). Ice slurries consist of suspen-sions containing a large number of small ice particles. WebLiquid-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 …
