Propulsion of a two-sphere swimmer (2015)
Journal Article
Klotsa, D., Baldwin, K. A., Hill, R. J., Bowley, R., & Swift, M. R. (2015). Propulsion of a two-sphere swimmer. Physical Review Letters, 115(24), doi:10.1103/PhysRevLett.115.248102

We describe experiments and simulations demonstrating the propulsion of a neutrally-buoyant swimmer that consists of a pair of spheres attached by a spring, immersed in a vibrating fluid. The vibration of the fluid induces relative motion of the sphe... Read More about Propulsion of a two-sphere swimmer.

The inhibition of the Rayleigh-Taylor instability by rotation (2015)
Journal Article
Baldwin, K. A., Scase, M. M., & Hill, R. J. (2015). The inhibition of the Rayleigh-Taylor instability by rotation. Scientific Reports, 5(11706), doi:10.1038/srep11706

It is well-established that the Coriolis force that acts on fluid in a rotating system can act to stabilise otherwise unstable flows. Chandrasekhar considered theoretically the effect of the Coriolis force on the Rayleigh-Taylor instability, which oc... Read More about The inhibition of the Rayleigh-Taylor instability by rotation.

Artificial tektites: an experimental technique for capturing the shapes of spinning drops (2015)
Journal Article
Baldwin, K. A., Butler, S. L., & Hill, R. J. (in press). Artificial tektites: an experimental technique for capturing the shapes of spinning drops. Scientific Reports, 5, https://doi.org/10.1038/srep07660

Determining the shapes of a rotating liquid droplet bound by surface tension is an archetypal problem in the study of the equilibrium shapes of a spinning and charged droplet, a problem that unites models of the stability of the atomic nucleus with t...
