• 中文摘要： 本研究係於內徑為5及7.5公分之透明壓克力流體化床中,觀察各種不同粒子之床行為,所用粒子之密度為0.9-6.86g/cm/sup 3/,粒徑為0.6-6mm之間,以空氣及氬為流體化氣體。以伽利略數為主要參數,繪出流動型態與氣速之關係圖,並依據文獻資料及本研究中所得之實驗數據,以統計法,求出預估床孔隙度及最小流體化速度之關係式。
• 英文摘要： An experimental study of the behavior of coarse particles (>0.5mm) of different sizes and densities fluidized in columns 5 and 7.5cm in diameter has been done. Minimum fluidization velocities measured in the 3-D equipment were found to be independent of bed height. Empirical correlations were proposed to estimate the minimum fluidization velocity and bed voidage. The flow regimes for various particles were observed, and the relationships between flow regimes and the Galileo number were investigated.
