| Outline of Final Research Achievements |
In this study, we conducted the development of the measurement technique for measuring the unsteady flow field around the collective motions of dispersed phase, and evaluate the effect of the dispersed phase motion on flow fields. We quantitatively measured velocity profile of the particle separation process in highly-concentrated dispersed multiphase flow. We also evaluated the effect of topological change of dispersed phase on the energy transport in a turbulent channel flow. As a result, we pointed out the non-uniform distribution of dispersed phase induce the modification of flow field.
