| Research Abstract |
Heat and mass transfer across an interface plays a central role in deciding the efficiency of various thermal fluids system, so that prediction and control of such phenomena should bring tremendous benefit in innovating energy saving technologies. In general, when heat/mass is transferred from an interface to surrounding fluid, a thin thermal/concentration boundary layer is formed in the very vicinity of the interface so that the overall transport is governed by the microscopic transport mechanisms in this thin layer. In the present study, we conduct a series of numerical simulations, which reproduce the multi-scale phenomena from the macroscopic turbulence far from the interface to the microscopic transport phenomena near the interface. Though these simulations, we clarify the relationship between the different scale phenomena and model them based on the database obtained in these simulations.
