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. WebErosion in slurry pumps occurs due to two mechanisms, viz., particle impact and sliding (scouring) action [5,6,7]. In dilute slurries, erosion is likely to be more due to particle impact [8]. Dilute slurry flow in slurry transportation is of significance in handling sewage, silted waters and certain dredging and mining applications. Webchamber for all flows.
