In order to better understand the role of the uid behavior in CMP, we measured slurry transport beneath a glass wafer. We quanti ed the slurry transport using Residence Time Distribution techniques and two measures of slurry transport e ciency de ned as the percentage of new slurry beneath a wafer. Slurry transport e ciency depended on platen speed, ow rate, and the conditioning method. We foun...

In order to explore the influence of gradation and concentration on rheological parameters uncemented coal gangue-fly ash backfill (UCGFB) slurry, based fractal theory, particle size distribution mixture gangue fly under different mixing ratios are analyzed in this paper. On basis, UCGFB slurry studied a numerical simulation transportation is also carried out. The results show that (1) dimensio...

The distribution of moisture, degradable C, and N after direct injection of slurry can affect the turnover and plant availability of slurry N. This study examined effects of injection method, soil conditions, and slurry properties on the infiltration of several slurry components under practical conditions. The water retention capacity of 22 pig and cattle slurries was quantified by dialysis at ...

This research was conducted to develop flowable slurry containing fibrous residuals from pulp and paper mills. Two types of flowable slurry containing ASTM Class C fly ash were produced: fly ash slurry and sandy slurry. Often, the fly ash slurry made without fibrous residuals showed a tendency to set rapidly, and become unworkable. When the cement-to-fly ash ratio was increased to extend the ti...

The wastewater generated in the potash mines of Bages region Catalonia (Spain) was experimentally tested at Paterson & Cooke slurry test facility Cape Town, South Africa, to determine flow behavior and limit deposition velocity various brine brine-slurry mixtures containing a low solids concentration fine insoluble particles. tests measured velocity, viscosity, resistance range different concen...

This research work is a significant step toward further understanding of the β-σ two-fluid model for simulation fully-suspended slurry flows in pipeline systems, with goal enhancing its potential scientific and engineering applications. Particularly, focus study characterization handling two main empirical coefficients model, namely, β σ, which require case-specific tuning based on given set ex...

Abstract Slurry flow (water–glass beads) through a horizontal pipe of diameter, 0.0549 m and length, 3.8 with two particle sizes, i.e., 125- 440-micron, has been numerically modeled investigated based on the kinetic theory slurry transportation. The effect particles interaction characteristics such as velocity profile, wall shear stress, vector regime, granular pressure temperature evaluated at...

Abstract Pipeline transportation is a process of continuous balance between pumping pressure and pipeline resistance. Therefore, accurate calculation resistance can optimize the accuracy pump model working parameters. The slurry transported in dredging project complicated, dredged soil different regions quite resulting motion states process. Different types flow patterns are suitable for models...

The use of slurry ice, both alone and in combination with ozone, as compared with traditional flake ice was investigated as a new refrigeration system for the storage of sardine (Sardina pilchardus). Microbiological, chemical and sensory analyses were carried out throughout a storage period of 22 days. According to sensory analyses, sardine specimens stored in ozonised slurry ice had a shelf li...

A study was undertaken on drained and undrained 1 ha grassland lysimeters to assess the effectiveness of multiple novel tracing techniques in understanding how agricultural slurry waste moves from land to water. Artificial fluorescent particles designed to mimic the size and density of organic slurry particles were found to move off the grassland via inter-flow (surface + lateral through-flow) ...
