Outline of Research
In our laboratory, we have been conducting basic research mainly focused on convective heat transfer. In many cases, fluid flow exhibits a very complex feature called “turbulence”. Therefore, convective heat transfer actually fluctuates in complicated manners in time and space, although such fluctuation is not visible. We have experimentally investigated the spatial and temporal nature of turbulent heat transfer in an effort to improve the reliability of thermal design and the thermal efficiency of equipment.
Also, we have been investigated passive flow control of a cylinder by attaching axisymmetric protrusions in order to reduce the drag force and to suppress the fluctuating force caused by vortex shedding.
