Gravitational effects on coffee-ring formation during the evaporation of sessile droplets (2023)
Journal Article
Moore, M., & Wray, A. (2023). Gravitational effects on coffee-ring formation during the evaporation of sessile droplets. Journal of Fluid Mechanics, 967, Article A26. https://doi.org/10.1017/jfm.2023.493

We consider the role of gravity in solute transport when a thin droplet evaporates. Under the physically relevant assumptions that the contact line is pinned and the solutal Péclet number, Pe , is large, we identify two asymptotic regimes that depen...

Near edge tractions for a rounded quarter-plane pressed into an elastically similar half-plane (2023)
Journal Article
Eames, B., Hills, D., & Moore, M. (2023). Near edge tractions for a rounded quarter-plane pressed into an elastically similar half-plane. Tribology International, Article 108582. https://doi.org/10.1016/j.triboint.2023.108582

Asymptotic forms are a useful way of representing the state of stress at a contact edge, allowing us to characterise the region in which cracks nucleate. The asymptotes must match the behaviour implied by the local geometry. In this paper, we study t...

Evaporation of non-circular droplets (2023)
Journal Article
Wray, A., & Moore, M. (2023). Evaporation of non-circular droplets. Journal of Fluid Mechanics, 961, Article A11. https://doi.org/10.1017/jfm.2023.229

The dynamics of thin, non-circular droplets evaporating in the diffusion-limited regime is examined. The challenging non-rectilinear mixed boundary problem this poses is solved using a novel asymptotic approach and an asymptotic expansion for the eva...
