The experiment for making of particle trajectory image analysis was almost carried out under glass beads particle (420 μ m diameter), layer high condition (layers high 50mm) in the two-dimensional fluidized bed of 80mm width, 150mm height, 3mm depth at pressure condition 0.1MPa. The consideration on the interaction of the bubble-inter-particle was tried, while features of the bubble behavior were understood, particle behavior of the bubble circumference though tracer particle painted black is entrapped in the particle bed, and though visualization image by transmitted light is acquired by the high-speed video, and though it refers to visual observation, PIV image analysis besides.
