.... Migrating increases the particle concentration in one direction and depletes the particle concentration in the other direction. This allows particle separation to occur. Experiments to separate large OxPure 1 612C-50 coconut carbon particles in Newtonian slurries were conducted using bump arrays...

... for erosion does relate to the yield stresses in a linear fashion for sufficiently large yield stresses. A criterion is developed to determine when the yield stresses may be important. shear stress erosion yield stress slurry settled bed Proceedings of the ASME 2024 Fluids Engineering Division...

... to the treatment facilities at low solids loading. Concentration is a necessary step to remove transport fluid and supernatant liquid. Several techniques are available to concentrate slurries including settle/decant, filtration, and evaporation that all present unique challenges. Using evaporators to dewater...

... Abstract Here we evaluate the performance of bump arrays to separate large particles from non-Newtonian slurries with Bingham and Cross rheology. Bump arrays in deterministic lateral displacement devices separate large particles from small particles using arrays of staggered posts. Large...

... Abstract Empirical wear coefficients are used in concert with computational fluid dynamics (CFD) codes which model highly loaded slurry flows through centrifugal pumps in order to predict erosive wear in wet-end components. In practice, separate sets of wear coefficients are used to determine...

... In summer 2012, an extensive measurement campaign was carried out in a new test loop composed of pipes of the internal diameter of 100 mm. Four fractions of glass ballotini were used for preparation of settling slurries of different properties. During the tests, different patterns of slurry...

... were obtained. With the increase in the particle volumetric concentration, fluctuation kinetic energy decreases and the maximum fluctuation kinetic energy typically occurs on the suction side of the blade. The slurry particles are pushed on the pressure side of the blade and slide on it which can...

... 03 03 2009 Particle Image Velocimetry (PIV) technique in conjunction with refractive index matching was successfully utilized to investigate the velocities of the slurry particles in the impeller of a centrifugal slurry pump. Tests were performed in an optically clear centrifugal...

... 04 03 2009 Transport of solid-liquid slurries in pipeline transport over short and medium distances is very important in many industries, including mining related processes. The particle image velocimetry technique was successfully utilized to investigate the velocities and kinetic...

... 05 02 2009 The purpose of a slurry pump is to transport solids in a mixture called a slurry. It is a critical component of the slurry transport system in many industrial and mining related processes. In this investigation, Particle Image Velocimetry (PIV) was successfully utilized...
