Particle laden flows through an inverted chimney with applications to ocean carbon sequestration
Plumes of negatively buoyant hydrate particles, formed by reacting liquid CO[subscript 2] with seawater at ocean depths of 1000–1500 m, have been suggested as a way to help sequester CO[subscript 2]. The vertical flux of CO[subscript 2] can be increased by constructing a shroud around the hydrate pa...

| description | Plumes of negatively buoyant hydrate particles, formed by reacting liquid CO[subscript 2] with seawater at ocean depths of 1000–1500 m, have been suggested as a way to help sequester CO[subscript 2]. The vertical flux of CO[subscript 2] can be increased by constructing a shroud around the hydrate particle source to shelter the plume from effects of ambient stratification and current. The shroud also serves as an inverted chimney, inducing a down draft that will transport the dissolving particles to a depth of lower ambient disturbance. Laboratory PIV measurements are compared to an analysis of an idealized shroud that is long, frictionless and driven by a single phase source of buoyancy distributed uniformly over the shroud base. Results indicate that induced draft, and hence dilution of dissolved CO[subscript 2], increases with plume buoyancy, and shroud length and diameter, but efficiency decreases with increasing ratio of particle slip velocity divided by the characteristic induced draft velocity. While larger particles show reduced plume-like behavior and hence are less efficient in inducing draft, they still generated about half of the theoretically predicted flow. |
