Viscoplastic boundary layers
(Cambridge University PressJournal of Fluid Mechanics, 2017-02-25)
In the limit of a large yield stress, or equivalently at the initiation of motion, viscoplastic flows can develop narrow boundary layers that provide either surfaces of failure between rigid plugs, the lubrication between ...
Stability of three-dimensional columnar convection in a porous medium
(Cambridge University PressJournal of Fluid Mechanics, 2017-10-25)
The stability of steady convective exchange flow with a rectangular planform in an unbounded three-dimensional porous medium is explored. The base flow comprises a balance between vertical advection with amplitude A in ...
Taylor's swimming sheet in a yield-stress fluid
(Cambridge University PressJournal of Fluid Mechanics, 2017-10-10)
A yield stress is added to Taylor’s (1951, Proc. Royal Soc. A, 209, 447-461) model of a two-dimensional flexible sheet swimming through a viscous fluid. Both transverse waves along the sheet, as in Taylor’s original model, ...
