Melting of ice slurry under forced convection conditions in tubes

Forced flow and convective melting heat transfer of clathrate hydrate slurry in tubes

“…12. Similar phenomenon was also observed by Yamagishi et al [28] in the study of MPCM slurry and Niezgoda-_ Zelasko and _ Zelasko [29] for ice slurry. It was believed that the degradation of the heat transfer coefficient resulted from the reduction of the turbulent degree caused by the laminarizing effect.…”

Experimental determination of the energy optimum for the transport of floating particles in pipes

“…In turbulent flow, particles could act as a drag reducer [49], as was observed by Knodel et al [35] for high flow rates with coarse ice slurry. This can be compared to the re-laminarization described by Niezgoda-Zelasko & Zelasko [2] for ice slurry flow. …”

“…Slurries suspensions transported through pipe-lines are essential for different applications and have drawn considerable attention in recent years in mining and mineral processing [1], ice slurry transport [2], pipeline transport of agricultural slurries in chemical plants, for example wheat straw and corn stover [3], sand removal [4], dredging and tailing disposal [5]. In many cases, the transported slurries consist of small size particles (usually up to a few tens of microns).…”

Entropy Generation of Forced Convection during Melting of Ice Slurry

“…Ice slurries are non-Newtonian fluids [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. The phenomena associated with flow resistance and heat transfer processes involving ice slurries have been extensively discussed in articles, such as [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 11 , 12 ]. A significant operational problem of ice slurry-fed systems is the elimination of phase segregation and ensuring a homogenous flow.…”

“…These phenomena make ice slurry heat transfer coefficients higher than those of single-phase refrigerants. For example, for ice slurries based on an aquatic solution of ethanol, in the laminar flow area, the presence of solid particles leads to a 2–5.7-fold increase in the heat transfer coefficient with respect to the heat transfer coefficients of the carrier fluid (ethanol x ai = 10.6% at −4.5 °C) [ 2 , 12 , 25 ]. On the other hand, there are some velocities at which for ice slurries with an ice content of x s > 10%–20%, the heat transfer coefficients are lower than those of the carrier fluid.…”
