The quantitative measurements of bed material movement and void fraction are indispensable for better understanding and formulation of thermal-hydraulics of fluidized bed. In this study the neutron radiography (NR) has been applied to the visualization of bed material movement and quantitative measurement of void fraction in the bed with 4×4 or 5×5 vertical tube banks. CT processing has also been employed to obtain void fraction distributions around the tube banks. The visualization data is expressed with the data of the heat transfer experiment, and the relationship between the heat transfer and void fraction is well correlated by Martin's correlation.
