dc.description.abstract | In this work the dynamics and dissolution of a hydratecovered CO2 drop were studied, using a numeric model and data from one of very few CO2 experiments performed in the real ocean. A theory including the standard drag curve of rigid spheres was shown not to fit the observed drop rise velocity. However, a drag parameterization supported by numerous laboratory experiments with gas bubbles provides a good match of the observed rise velocity of a liquid CO2 drop covered with hydrate. The results confirm laboratory results showing that shape is a key factor determining the CO2 drop dynamics. We also found that hydrate reduces the mass transfer of the observed drop by a factor of 2, which is compatible with laboratory experiments. Numerical experiments with different drop sizes showed that the choice of drag parameterization has a significant impact on the estimated vertical distribution of dissolved CO2. | en_US |
