Study of the filter cake formed due to the sedimentation of monodispersed and bidispersed particles using discrete element method–computational fluid dynamics simulations

Abstract: This study aims to investigate the sedimentation and the consolidation of the packed bed/cake formed due to the monodispersed and bidispersed particles under different flow conditions. Mutual interactions between the bidispersed particles and the liquid are considered by using a polydispersed drag model. The attractive force is considered by using the JKR model. Sensitivity of the void fraction of a sedimented packed bed/cake due to particle–particle interaction parameters is studied. Furthermore, the effect o… Show more

“…The study employs a coupled Large Eddy Simulation -Discrete Element Method (LES-DEM) model, provided and coded by previous studies (e.g., Kloss et al, 2012). The model belongs to CFD-DEM models, which have had considerably improved our understanding of particle-laden flows in recent years (e.g., Tsuji et al, 1993;Peng et al, 2014;Tsuji et al, 2008;Deen et al, 2007;Smuts, 2015;Deshpande et al, 2019;Zhu et al, 2007Zhu et al, , 2008Jing et al, 2016;Jing et al, 2018;Zhang and Yin, 2018), most notably sediment transport (Zhao and Shan, 2013;Li and Tao, 2018;Li and Zhao, 2018;Sun et al, 2018;Xiao, 2016a, 2016b;Furbish and Schmeeckle, 2013;Schmeeckle, 2014;Zhao et al, 2014;Lu et al, 2019;Zhang et al, 2020;Durán et al, 2012;Maurin et al, 2015;Maurin et al, 2018;Pähtz and Durán, 2018a, 2018b, though their application to TCs have been rather limited (Meiburg et al, 2015;Biegert et al, 2017).…”

“…Therefore, the reduced coefficient of restitution is used to model the lubrication force, as done by Kidenemariam and Uhlmann [69] and Deshpande et al [70] in their studies. Same approach is applied in this study and the coefficient of restitution, which is input parameter for DEM, is reduced and set to 0.3.…”

“…These studies used a continuum approach instead of a particle‐based simulation method; with a continuum approach, a microphysical interpretation was not possible. Moreover, there are various simulation studies on cake filtration 5, 15, 16. However, these studies did not aim to describe the local filter cake properties gained from CP cell experiments.…”
