Three-dimensional direct numerical simulation (DNS) is applied to a wind-driven air-water two-phase flow, and the turbulence structure in boundary layers on both gas and liquid sides and the scalar transfer mechanism across the air-water interface are investigated. In order to capture the moving air-water interface, an Arbitrary Lagrangian Eulerian formulation (ALE) method is employed. The results show that the scalar transfer across the wind-driven air-water interface is mainly controlled by the streamwise vortices related to bursting motions on the liquid side.
