FYI - seminar on Monday re. ice sheet dynamics

Dear all,

Please join us for a Mathematical Modelling of Fluid Mechanics seminar on Monday 15th May at 4.30pm (Sydney/Melbourne time).

We are delighted to have Dr Katarzyna Kowal (University of Glasgow) giving a talk on Thin-film flows: why substrates matter. Abstract below. Zoom link.

If you haven’t already, you can join the seminar series mailing list here. And please forward this email to any of your students or colleagues who would be interested.

Best wishes,

Ed Hinton

Thin-film flows: why substrates matter

Dr Katarzyna Kowal (University of Glasgow)

Thin-film flows are ubiquitous in nature and industry, with a range of geophysical, environmental and industrial applications. Many of these exhibit vastly different dynamics when spreading over different substrates. Examples include the dynamics of large-scale ice sheets, which flow orders of magnitude faster when lubricated from below, and a range of flows over hydrophobic surfaces, which promote drag reduction. In this talk, we will examine the role of the substrate, specifically how well it is lubricated and how it deforms, on the flow of an overlying thin film of viscous fluid, and relate our findings to the flow of ice sheets and the geophysical features that form as a result. A particularly intriguing feature involves the formation of so-called grounding zone wedges, or accumulations of soft, subglacial till in ice-sheet grounding zones, separating ice sheets that are grounded over bedrock from freely floating ice shelves.
