“…Computational fluid dynamic (CFD) is the most widely used [ 131 ] and is usually combined with other techniques like discrete element method (CFD-DEM) model [ [132] , [133] , [134] , [135] ]. Also, the development and application of dynamic model [ 136 ], dynamic and steady-state model [ 137 ], Rosin-Rammler model [ 138 ], and soft sensor model [ 120 ] have been reported. System controls (i.e., smart sensor [ 130 ], model-data-based switching adaptive control [ 139 ], pump-storage system [ 140 ], medium density control [ 141 ], dual-loop control system [ 142 ], and intelligent control [ 143 ]) were also applied to measure and optimize separation.…”
