Energy transfer mechanism in a vibrating fluidized bed

A novel methodology for simulating vibrated fluidized beds using two-fluid models

“…Experimental studies on the overall aerodynamics of vibrated fluidized beds have shown that VFB operates with lower minimum fluidization velocity, and pressure drop [11,12] providing a higher homogeneity and stability of the fluidized bed. Bubble characteris tics such as bubble size, shape or ascending velocity are important parameters that have been extensively studied in conventional FB operating in the bubbling regime since they affect their perfor mance as reactors [13 17].…”

Recent developments in drying of food products

“…The type of dryer used is based on the need and the desired properties of drying products. Some of the new systems like desiccant [41], electro hydrodynamic and hybrid dryers [29], vibrated fluidized bed [19]& [48], fluidized bed [37]& [43], freeze [2]& [34], hot air drying [9], infrared [13,14], [16], intermittent [11], microwave [21], [49] & [53],and vacuum [44] have been utilized and investigated by researchers for drying the food products.…”

“…It is observed that electroporated tissue samples shows large pores, fast rate of moisture impregnation and large rehydration capacity hence reported that PEF treatment gives better results.Ronak Daghigh et al [39] carried out a review of solar assisted heat pump drying systems for agricultural and marine products.Ruifang Wang et al [40] carried out drying experiments using a hybrid microwave rotary drying system in soybean drying and studied the effect of drum speed, cracking ratio, etc. Ting -Jie Wang et al [45] analyzed and reported the mechanism of vibration energy transfer using wave propagation. Sensors have been used to detect the wave signals produced and calculate the pressurewave propagation parameters.…”

The effect of vibration on bed voidage behaviors in fluidized beds with large particles

“…Tatemoto et al (2005) adopted the discrete element method to simulate cohesive particle motion characteristics in vibrating fluidized beds. Wang et al (2000Wang et al ( , 2002 analyzed the resonance characteristics and bed wave propagation process and reported the energy transfer mechanism in a vibrating fluidized bed.…”
