| Research Abstract |
The measurements in a wind-wave tank with a rain generator shows that mass transfer across the wind-sheared air-water interface is promoted by rainfall and that the mass transfer coefficient in the combined condition with both rainfall and wind-shear is generally estimated by the sum of the individual mass transfer coefficient for rainfall and that for wind-shear. In addition, both experimental and numerical predictions show that the impingement of a single liquid drop on the water surface generates the surface renewal motion on the liquid side and enhances the mass transfer across the air-water interface.
