Краткое описание
According to research performed for nearly fifty years, the fluidization of fine powders is complex. The difficulty of putting these powders in suspension in the fluidizing gas is related to the cohesive structure and, in particular, to the physical forces between the primary particles. The basic aim of this research work was to improve the quality of fluidization of Marble powder (dp = 90 μm) by applying external source in terms of acoustic field. Also, effect of acoustic field on minimum fluidization velocity (Umf ) has been found out at resonant frequency. The value of Umf at 145 dB and 120 Hz is found to be 0.72 cm/s which was very less compared to Umf 0 at without sound intensity i.e., 1.6 cm/s. It was also noted that bed expansion (H) is marginally improved compared to without application acoustic field.
