Prediction of CO2/CH4 droplet/bubble dispersion and dissolution in seawater

There is a concern, which might be a key factor as consideration of engineering application of CO2 under seabed storage, that is what would be the impacts on marine organisms when stored CO2 leaks accidentally either from CO2 injection well or from seabed. On the other hand, the pollution gases (CH4, H2S, and others) in geoformation/sediments may migrate to the water column, which are also the concerns of marine impacts created by, especially by the fishery. In this study, you will develop an assessment model to estimate how the physicochemical impacts may developed by those leaked gases and the possibility to migrate back to the atmosphere to enhance the global worming. By means of developed model, you will be able to predict the dynamics of gas bubbles rising velocity, shrinking rate and final terminal time with respect to initial sizes and leakage depths. Those are useful data for prediction of impacts on marine organisms and the date for assessing further the applicability of CO2 undersea bed storage. The target ocean can be the North Sea, for which the oceanic data (pressure, temperature, salinity, currents,..) will be predicted by a regional scale ocean model together with the data observed from field experiment carrying out at Golden-Eye site from an EU project STEMM.
