Advances in research on flow performance of acoustic fluidized bed

Acoustic fluidized bed is formed by introducing a sound field into a fluidized bed filled with particles as bed matrix.Acoustic field can reduce particle agglomerate size,and dramatically improve the fluidization quality of particles.The principle of acoustic fluidized bed and the progress of basic research and application of acoustic fluidized bed are presented.The research of acoustic fluidized bed including hydrodynamics characteristics,particle characteristics,sound field parameters,fluidization model,particle agglomeration and mechanism of fluidization is reviewed.The existing problems and the development of acoustic fluidized bed technology are proposed.
