✦ Synopsis

Three-dimensional numerical simulations of a horizontal rotating fluidized bed (RFB) containing glass bead particles (d s = 82 μm, ρ s = 2450 kg/m 3 ) and washed alumina (d s =89 μm, ρ s = 1550 kg/m 3 ) were performed. FLUENT 6.1 software was used to carry out our simulation. The numerical results were compared with the experimental data of Qian and Pfeffer et al. [G.H. Qian, I. Bagyi, I.W. Burdick, R. Pfeffer, H. Shaw, Gas-Solid Fluidization in a Centrifugal Field." AIChE J. 47 (5) (2001) 1022-1034]. The rotating speed of the RFB was set at 325 rpm (34 rad/s), which is equivalent to a centrifugal acceleration of 7 g.

The flow behavior of the solid particles was analyzed; the bed thickness and the calculated pressure drop were compared with the experimental results. Our calculated pressure drop agreed very well with the experimental results.
