Abstract
In order to evaluate of physical quantities transformed through Atmosphere-Ocean interface, we performed two-phase flow simulations by means of C-CUP (CIP-Combined Unified Procedure) method for deformable free-surface flow with high wind shear. According to analysis of turbulent statistics, it was suggested that vertical velocity fluctuation became large near air-liquid free-surface, and mechanism for transportation of turbulent energy at the gas-phase into the liquid-phase by Reynolds stress produced by the fluctuating free-surface corresponded well with results of wind-wave tank experiments. Moreover, it was suggested that the evaluated values for both frictional stress and root-mean-square of free-surface fluctuation under corresponding mean wind velocity were in good agreement with results from previous experiments. Therefore, in this study, it was shown that numerical simulation with C-CUP method might represent realistic momentum transportation processes in air-liquid systems.
