内容記述 | Local frictional drag and local void ratio in the flow with microbubbles were measured in the high speed small circulating water tunnel, by systematically changing the average void ratio and the main flow velocity and the measurement position from the microbubble injection point. The velocity distribution of microbubble-flow was also measured by using PIV (Particle Image Velocimeter). The results indicate that the local void ratio near the wall is important for efficient frictional drag reduction. | |||||
