    초록 Characteristics of turbulent flow and mass transfer around a rotating circular cylinder are investigated by direct numerical simulation. Mass-transfer results are presented at a high Schmidt number (Sc=1,670). The concentration field is computed for three different case of Reynolds number, Re*R=161, 348, 623, based on cylinder radius and friction velocity. Results confirm that the thickness of Nernst diffusion layer is very small compared with that of viscous sub-layer in the case of high Sc mass transfer. A strong correlation of the concentration field with streamwise and vertical velocity components is noticed. However, that is not the case with the spanwise velocity component. The correlation between Sherwood number and Reynolds number is consistent with other experiments currently available.
