Gas-solid fluidization is characterized by pervasive, dilute-dense two-phase flow structures, which need mesoscale drag modeling to account for their subgrid effects. The classic formulation of the energy-minimization multi-scale (EMMS) drag modeling requires a semi-empirical correlation of cluster diameter. Novelty lies in the use of numerical models (Model B2 and B3) with drag coefficients tuned based on the limited-DoF drag model (Model A) free decay in addition to the experiment-based drag-coefficient-tuned model (Model B1). The proposed novel method of tuning (Model B2 and B3) produced global load approximations that are on a par or even ...... Drag Mode and Trans Brake provide incredible versatility—and Drag ...
