Three-dimensional capillary waves due to a submerged source with small surface tension
Christopher J. Lustri, Ravindra Pethiyagoda, S. Jonathan Chapman
Steady and unsteady linearised flow past a submerged source are studied in the small-surface-tension limit, in the absence of gravitational effects. The free-surface capillary wave…
On the boundary layer structure near a highly permeable porous interface
Mohit P. Dalwadi, S. Jonathan Chapman, Sarah L. Waters +1
The method of matched asymptotic expansions is used to study the canonical problem of steady laminar flow through a narrow two-dimensional channel blocked by a tight-fitting finite…
Diffusion in spatially varying porous media
Maria Bruna, S. Jonathan Chapman
The problem of diffusion in a porous medium with a spatially varying porosity is considered. The particular microstructure analyzed comprises a collection of impenetrable spheres,…
Curvature suppresses the Rayleigh-Taylor instability
Philippe H. Trinh, Hyoungsoo Kim, Naima Hammoud +3
The dynamics of a thin liquid film on the underside of a curved cylindrical substrate is studied. The evolution of the liquid layer is investigated as the film thickness and the ra…
Threshold amplitudes for transition to turbulence in a pipe
Lloyd N. Trefethen, S. J. Chapman, Dan S. Henningson +3
Although flow in a circular pipe is stable to infinitesimal perturbations, it can be excited to turbulence by finite perturbations whose minimal amplitude shrinks as R goes to infi…
