| 英文摘要 | In this study, the effects of the type of pulsating inlet waveform, pulsation frequency, and pulsation amplitude on the stability of fluidized beds and the erosion of immersed tubes were investigated by numerical simulation. Compared with rectangular and triangular inlet flows, sinusoidal flow induced the lowest immersed-tube erosion rate and pressure-drop fluctuation in the fluidized bed. Furthermore, under sinusoidal flow with a pulsation frequency of 1 Hz and pulsation amplitude of 0.25um, the immersed-tube erosion rate was lower by 1.8 %, standard deviation of pressure drop by 14.16 %, and energy generated from bubble rupture by 47.83 % than those under uniform flow. A dimen-sionless parameter vp that can represent immersed-tube erosion during pulsating flow was proposed, which reflects the effect of particle flow characteristics, particle fluidization degree, and pulsation fre-quency on immersed-tube erosion.CO 2023 Elsevier Ltd.
