Research Abstract

The following 3 articles are achieved.
In this study, quantification of turbulence events and bubble behavior are provided by the development of Time - y-axis imaging analysis based on behavior of individual particle and bubble. The turbulence event and bubble are summarized into three points. (1) Frictional drag characteristics in turbulent horizontal channel bubbly flow by using shear stress sensor. (2) Wall shear stress fluctuations indicate that the bubble injection produces quasi-random fluctuations that eliminate positive spikes on the fluctuations in turbulent flows. This elimination takes primary role on the drag reduction in the present case that the bubble deformations are allowed. (3) Frictional drag characteristic of single bubble and clustering bubble are clarified. Drag reduction map is renewed including clustering bubbles
