Abstract

Joe: Dissolution of salt caverns for hydrogen storage

The low permeability of salt rock (halite) means salt caverns can be used for long term storage of large amounts of hydrogen. I will introduce some analogue experiments and simple modelling to investigate how the size and shape of these caverns evolve as they are artificially created.

Maggie: Could bubble curtains slow down marine glacier melt?

Bubble plumes (or fluid curtains more broadly) are effective at separating transient buoyancy-driven flows in a variety of engineered settings such as ship locks and supermarket displays. I am interested in investigating the proposed efficacy of similar fluid barriers in separating long-term heat exchange between the semi-infinite heat reservoir of the ocean from the finite heat reservoir of an ice shelf. I will present some early work in thinking about the problem only as mass/concentration exchange across control volumes and (very) preliminary data from laboratory experiments.

Jacob: Freezing Porous Gravity Currents

Motivated by recent interest in Arctic sea ice thickening, we explore porous gravity currents undergoing freezing through experimental work which we compare to non-freezing porous gravity current theory.
