| Outline of Final Research Achievements |
In this study, we simulated and explored the complex turbulent heat and mass transport processes in forced convection regime with separation and reattachment by wind-tunnel experiment and direct numerical simulation (DNS). As a complex turbulent flow, we mainly investigated the effects of the thermal boundary condition on heat transfer characteristics over two-dimensional hill model, and we tried to understand the elementary processes based on the superposition principle. Moreover, we developed an accurate temperature measurement using the response compensation based on the frequency transfer function and a smaller-sized concentration detector specially designed for separated turbulent flows.
