The motion mechanism and characteristic of bubble in a pseudo-2D tapered fluidized bed
文献摘要：
The different carbon nanotube(CNT)particles(@A and@V)were bed materials in the pseudo-2D tapered fluidized bed(TFB)with/without a distributor.A detailed investigation of the motion mechanism of bub-bles was carried out.The high-speed photography and image analysis techniques were used to study bubble characteristic and mixing behavior in the tapered angle of TFB without a distributor.The fractal analysis method was used to analyze the degree of particles movement.Results showed that an S-shaped motion trajectory of bubbles was captured in the bed of@V particles.The population of observational bubbles in the bed of@V particles was more than that of@A particles,and the bubble size was smaller in the bed of@V particles than that of@A particles.The motion mechanism of bubbles had been shown to be related to bed materials and initial bed height in terms of analysis and comparison of bubble diam-eter,bubble aspect ratio and bubble shape factor.Importantly,compared to the TFB with a distributor,the TFB without a distributor had been proved to be beneficial to the CNT fluidization according to the study of bubble characteristic and the degree of the particle movement.Additionally,it was found that the mixing behavior of@V particles was better than@A particles in the tapered angle of TFB without a distributor.
