WebApr 2, 2014 · A single-phase 3D model for isothermal laminar and turbulent flow of an ice slurry in a horizontal pipe is used to investigate the effects of the uniform inlet velocity and ice concentration on their axial evolution. The slurry is modeled as a Newtonian fluid with effective local properties depending on the local ice concentration. Despite the relative … WebJan 15, 2009 · The heat transfer and pressure drop characteristics of forced convection flow of slurry ice that contains ice particles with 0.5--1 mm diameter was experimentally presented in this paper. The heat transfer coefficients agreed with Dittus-Boelter's equation. The pressure drop agreed with Blasius' equation at high velocity and low IPF of slurry ice.
WebMay 9, 2024 · The dynamics of three-phase flows involves phenomena of high complexity whose characterization is of great interest for different sectors of the worldwide industry. In order to move forward in the fundamental knowledge of the behavior of three-phase flows, new experimental data has been obtained in a facility specially designed for flow … 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.
