The effect of slip along a Gaussian-shaped gap deformity, located about a fixed position on the lower wall of a two-dimensional channel, is numerically investigated. Two gap deformations are modelled, with dimensions sufficient to generate localised

The unsteady flow due to a sphere, immersed in a quiescent fluid, and suddenly rotated, is a paradigm for the development of unsteady boundary layers and their collision. Such a collision arises when the boundary layers on the surface of the sphere a

A computational study shows that the flow induced by a sphere rotating in an otherwise quiescent fluid is convectively unstable to spiral vortices, which once induced are swept down through the sphere's boundary layer and then out into the radial jet

We present results of a study on the roughness-induced receptivity of the boundary layer that exists in the flow due to a rotating sphere. Our approach exploits a computational methodology that allows us to capture the full range of fundamental fluid

Imparting a sudden rotation to a torus (or other symmetric smooth object) in an otherwise quiescent, viscous fluid serves to generate boundary layers at the object’s surface. These boundary layers are known to exhibit a finite-time singularity at t

We consider the behaviour of the flow within a fluid-filled torus when there is a sudden change in the rotation rate of the torus. Experimental work on this problem by Madden & Mullin (J. Fluid Mech., vol. 265, 1994, p. 217) demonstrated a flow with

We consider the flow induced by a sphere, contained in an otherwise quiescent body of fluid, that is suddenly imparted with angular momentum. This classical problem is known to exhibit a finite-time singularity in the boundary-layer equations, due to
