“…Although their simulations involved particle sizes \0.1 mm, Altway et al 22 showed that the pattern of solid concentration contours for different particle sizes was qualitatively similar; however, smaller particles showed a more uniform distribution. Using larger particles with 0.1 mm \ d \ 0.5 mm, Š pidla et al 23 experimentally confirmed by means of a conductivity probe that smaller solid particles generate a more homogeneous suspension. Their results also showed that the homogeneity of the solid-liquid suspension improved with increasing average solid concentration.…”

The three-component flow field and spatial phase distribution of binary mixtures of glass particles suspended in water in a stirred vessel have been resolved using positron emission particle tracking (PEPT). The Lagrangian flow data provided by the technique have been converted to give a detailed Eulerian description of each of the three phase components of the flow generated by a pitched blade turbine. For the first time, it has been possible to determine the full 3D velocity and concentration fields of the liquid phase and both the solid components within opaque dense slurries of this type containing up to 40 wt % solids. Spatial distributions of local time-averaged slip velocity have also been obtained for each solid component showing wide variations. The detailed PEPT measurements have enabled the solids mass balance and the mass continuity of the three phase components to be accurately verified throughout the vessel.

“…Hence there is a need for a non-invasive, inexpensive, rapid online-method that monitors qualities such as solid content, sedimentation and the effects of the additives. In addition to the traditional measurements, alternative methods have been developed based on ultrasound [5][6][7], microwaves [8] and electrical conductivity [9][10][11].…”

A novel, cheap and simple technique for the analysis of the mixing properties from a stirred vessel is introduced. The technique is based on a digital imaging technique and the analysis can be undertaken based on the properties of the image. Using this technique, it is easy to analyze mixing inhomogeneities. Test measurements with non-Newtonian viscous, aqueous xanthan solutions and fluids as well as liquid-particle suspensions showed that the developed method is a quick and quantitative tool for the analysis of local mixing inhomogeneities, mixing times and particle suspension speeds.
