1303 風波気液界面を通しての二酸化炭素移動に及ぼす降雨の影響(OS13-1 大気海洋の流体現象と環境流体,オーガナイズドセッション)

Abstract

The effects of rain on CO_2 transfer across the wavy-sheared air-water interface were investigated through reaeration experiments of CO_2 in a wind-wave tank with a rain generator. The CO_2 transfer coefficient on the liquid-side k_L was measured by applying the mass-balance method. The results show that CO_2 transfer across wavy-sheared air-water interface was promoted by rain. The measured values were not in good agreement with the empirical formula proposed in previous paper, since the impinging velocity of raindrops was not considered in the literature.
