 note = {本研究では，流動床インターフェース中の物体に働く浮力を計測するほか，その結果を用いて流動状態にある砂のかさ密度を求めた．, Net buoyancy force acting on an object immersed in Fluidized Bed Interface was measured and the bulk density of fluidized bed surface was calculated. Air/ceramic sand fluidized bed was operated at 70-100 V with a spherical weight immersed at the depth of one to four times of its diameter. The result demonstrates Archimedes’ principle is applicable at the depth of less than two times of the diameter. However, the object sinking at three to four times of the diameter shows a negative net buoyancy force, which suggests the existence of defluidized hood at the top of the object.},
