Influence of disposal depth on the size of CO2 droplets produced from a circular orifice
Disposal of liquid, anthropogenic CO2 in intermediate-depth ocean waters has been accepted as a means to reduce atmospheric concentrations of this greenhouse species and mitigate global warming. Since the CO2-seawater system is hydrodynamically unstable, liquid CO2 effluent in the ocean will break up into droplets. This paper discusses the influence of both the discharge orifice and properties of CO2 and seawater on the size of CO2 droplets produced. It is found that the droplet size is affected strongly by disposal depth. This suggests that determination of the behavior of CO2 discharged in the ocean must consider not only the orifice configuration, but also fluid properties at the disposal site.
