| Research Abstract |
The measurements in a wind-wave tank without rainfall show that the effects of fetch, salinity and entrained bubbles on mass transfer across the wind-sheared air-water interface are negligibly small. The measurements in a wind-wave tank with a rainfall show that the mass transfer coefficient promoted by raindrops’impingement is well correlated with the vertical momentum flux of rainfall. In addition, both experimental visualization of water flow induced by a falling drop and numerical predictions show that the impingement of a single liquid drop on the water surface generates the downward flow on the liquid side and enhances the mass transfer across the air-water interface.
