Experiments and CFD Predictions of Solid Particle Distribution in a Vessel Agitated with Four Pitched Blade Turbines

Experimental Characterisation and Modelling of Homogeneous Solid Suspension in an Industrial Stirred Tank

“…Due to the very small influence of lift, Basset, and virtual mass forces on the simulated solid hold-dup profile [12], only the drag force may be considered in the interphase momentum exchange term (Schiller-Naumann). Results obtained using these two models are available in the literature and show that the Eulerian Multiphase model [13][14][15] is more accurate than the Eulerian Mixture model [16,17] when working with particle size higher than 100 m and solid fraction ranging between 0.2 and 16%,. Nevertheless, the Eulerian Mixture model is less time consuming and well adapted for low particle size (<10 m) and concentration (<0.1%) and should be suitable in our case.…”

Models and Applications for Simulating Turbulent Solid&#x2013;Liquid Suspensions in Stirred Tanks

“…Various solid-liquid suspension systems with solids fractions ranging from dilute to dense have been simulated by using the E-E approach, and the solid particle distributions have been validated and verified by many researchers (Altway et al, 2001;Barrue et al, 2001;Montante et al, 2001;Špidla et al, 2005;Fletcher and Brown, 2009;Liu and Barigou, 2013;Tamburini et al, 2013). The effects of other parameters including the particle size (Sha et al, 2001;Ochieng and Lewis, 2006b), mixed particles with different densities (Montante and Magelli, 2007), the Schmidt number, the laminar viscosity coefficient (Montante et al, 2002;Shan et al, 2008), and scale-up criteria (Montante et al, 2008) on the solids concentration distribution have also been discussed.…”

Long-time Solids Suspension Simulations by Means of a Large-Eddy Approach

“…The configurations all had a height (H) over diameter (T) aspect ratio of 4, and were equipped with four equally spaced impellers. Montante et al (2001) numerically studied the case of four pitched blade impellers revolving in a baffled tank. In this article, we will consider the case of an unbaffled tank with hydrofoil Lightnin A310 impellers.…”
