In recent years there have been numerous studies on floating films of non-Newtonian fluids due to their application to model the stability of floating ice shelves. Sayag & Worster (2019) showed theoretically that expanding cylinders of shear-thinning fluids can become non-axisymmetrical at the advancing fluid edge, driven by their non-Newtonian rheology. This instability carries over to radially spreading, thinning films of the same material when that fluid floats on a deeper bath of less viscous, but denser, Newtonian fluid.

Experimentally validating these theoretical results has, however, been challenging. Initial experimental exploration using Xanthan gum floating on a dense bath of salt solution shows dramatic non-axisymmetrical patterns. These patterns have their origin in interfacial effects, rather than Sayag & Worster's instability, with the expanding film appearing to fracture under extensional stresses at the fluid edge (Ball et al., 2022).

In this talk, I will present a new set of experiments exploring the instability, in which spreading films of aqueous suspensions of Carbopol and Xanthan gum are floated on a bath of more dense perfluorinated oil. The immiscibility between the bath and floating film prevents the failure of the material under tension and allows comparison against theoretical predictions from a shallow film model (Ball & Balmforth, 2021; Ball & Balmforth 2025).

The Oil and Society research network welcomes all staff and students to a presentation with professor Gavin Bridge (Durham University). Professor Bridge will present ongoing work (with James Marriott) under the heading "What now for the UK oil complex?"
