Rheology Characteristics and Critical Velocity of Particle-laden Flow Affected by Three-lobed Spiral Pipe

Behavior of a particle-laden flow in a spiral channel

Spiral gravity separators are devices used in mineral processing to separate particles based on their specific gravity or size. The spiral geometry allows for the simultaneous application of gravitational and centripetal forces on the particles, which leads to segregation of particles. However, this segregation mechanism is not fundamentally understood, and the spiral separator literatures does...

investigation of the velocity distribution in sediment-laden flow

introduction: for a velocity profile in turbulent flows, the flow conditions in the vicinity of the wall are described by logarithmic law of the wall. however, it has been extensively verified that the log-law does not apply in the outer region of the boundary layer. for example, in free surface flows, the law of the wall holds only for 20 percent of the flow depth from the wall. coles (1956) c...

Flow and Convective Heat Transfer Characteristics of Spiral Pipe for Nanofluids

This paper presents an experimental investigation of convective heat transfer coefficient for nanofluids using spiral pipe heat exchanger. The aim of this study is to investigate experimentally flow and convective heat transfer characteristics of water-based nanofluids flowing through a spiral pipe. The test section consist of spiral pipe with ratio pitch per diameter is 7.0 and mean hydraulic ...
