| Outline of Final Research Achievements |
We focused on the fluid-related phenomena at the mesoscale between the molecular theory and continuum. We have developed several techniques of measurement data analysis typically obtained from microscopy, where Brownian particles are suspended in fluid. In particular, we have enabled distinction of mixed data of displacements originating from partial adsorption or confused tracking. Furthermore, we developed a novel technique that enables the quantitative evaluation of diffusion field just like velocity field in the PIV analysis. On the other hand, we have also revealed a universal property in the transport of Brownian particles with spherical symmetry through a channel with the height similar to the particle diameter. This is not predicted from macroscopic theories of fluid mechanics, but it can also be described in terms of (the inverse of) Peclet number. We have also shown several case studies where mesoscale dynamics is of fundamental importance in the engineering applications.
