This article describes the flow around bluff body in microbubble plume. Firstly, the flow around two circular cylinders arranged in tandem within a microbubble plume was investigated. The experiment revealed the water and bubble shear layers originating at the sides of the lower cylinder, and allowed the elucidation of their behavior around the upper cylinder. Secondly, the motion of a solid spherical particle in a microbubble plume and the behavior of bubbles around the particle were studied. The studies clarified the bubble distribution and velocity around the particle.
