WebJun 30, 2024 · In this study, the multi-phase Eulerian–Eulerian two-fluid method (TFM) coupled with the kinetic theory of granular flow (KTGF) was used to investigate the hydrodynamics of particle flows (Geldart Group B) in a lab-scale bubbling fluidized bed. The goal was to improve the bubble flow behavior inside the fluidized bed to improve the … WebBased on Equations (18)–(20), variations of μ B and C B were obtained at an interval of T = 360 s. As β B and < I BC > showed stable variations over time, μ B and C B remained constant over the specific duration of the test as shown in Figure 5A,B. Thus, μ B and C B were represented as average ± standard deviation (n = 5).
