Surface-tension-driven evolution of a viscoplastic liquid coating the interior of a cylindrical tube

JD Shemilt, A Horsley, OE Jensen… - Journal of Fluid …, 2022 - cambridge.org
One mechanism for airway closure in the lung is the surface-tension-driven instability of the
mucus layer which lines the airway wall. We study the instability of an axisymmetric layer of …

Falling liquid films in narrow tubes: occlusion scenarios

GF Dietze, G Lavalle, C Ruyer-Quil - Journal of Fluid Mechanics, 2020 - cambridge.org
We study a gravity-driven wavy liquid film falling down the inner surface of a narrow
cylindrical tube in the presence of an active core gas flow. We employ the model of Dietze …

Motion of Long Levitating Drops in Tubes in an Anti-Bretherton Configuration

P Favreau, A Duchesne, F Zoueshtiagh, M Baudoin - Physical Review Letters, 2020 - APS
In his seminal paper, Bretherton studied the motion of long bubbles in capillary tubes. Here,
we unveil the negative configuration wherein a long liquid drop is stably transported in a …

The effect of isolated ridges and grooves on static menisci in rectangular channels

EC Johnstone, AL Hazel, OE Jensen - Journal of Fluid Mechanics, 2022 - cambridge.org
We present theoretical and numerical results that demonstrate the sensitivity of the shape of
a static meniscus in a rectangular channel to localised geometric perturbations in the form of …
