The numerical analysis of bifurcation problems
Two immiscible fluid layers that are subjected to a temperature gradi-ent perpendicular to their interface, exhibit a range of behaviors that is considerably richer than for the single-fluid case. We...
Stability of the O(2)-symmetric ow past a sphere in a pipe (2008)
We examine the linear stability of the O(2)-symmetric laminar ow past a centrally-located sphere in a pipe for a range of sphere sizes. For all values of the blockage ratio studied, the rst...
Structure-activity relations in Cs-doped heteropolyacid catalysts for biodiesel production (2007)
Narasimharao, K., Brown, D.R., Lee, A.F., Newman, A.D., Siril, P.F., Tavener, S.J., ...
NMR and IR study of fluorobenzene and hexafluorobenzene adsorbed on alumina (2007)
Budarin, V.L., Clark, J.H., Hale, S.E., Tavener, S.J.
The adsorption of fluorobenzene (C6H5F) and hexafluorobenzene (C6F6) onto the surface of neutral alumina is investigated by reflectance IR spectroscopy, near-IR spectroscopy, and measurement of 19F...
Starbons: new starch-derived mesoporous carbonaceous materials with tunable properties (2006)
Budarin, V., Clark, J.H., Hardy, J.J.E., Luque, R., Milkowski, K., Tavener, S.J., ...
A star is born: The complex molecular architecture found in plants is used in the design of new nanostructured materials. Carbon-based mesoporous materials with tunable surfaces and bulk properties...
Macquarrie, D.J., Tavener, S.J., Harmer, M.A.
Perfluorinated sulfonic acids have been immobilised into mesoporous silica frameworks by a one-step process, representing the first example of the successful incorporation of charged silanes using...
Implementation of extended systems using symbolic algebra (2000)
Following the pioneering work of Keller and others in the 1970s and ’80s, numerical techniques for solving non-linear systems of equations that exhibit bifurcations have been developed to the point...
The Freedericksz transition as a bifurcation problem (1998)
G. I. Blake, T. Mullin, S. J. Tavener
Abstract. We consider the eþ ects of the application of electric and magnetic ® elds to a homogeneously aligned nematic liquid crystal which lies between parallel plates. The average alignment of...

Marangoni–bénard Convection, K. A. Cliffe, S. J. Tavener
Computations of Marangoni convection are usually performed in two- or threedimensional domains with rigid boundaries. In two dimensions, allowing the free surface to deform can result in a solution...
An orthogonal mapping technique for the computation of a viscous free-surface flow (1992)
Cliffe, K.A., Tavener, S.J., Wheeler, A.A.
In this paper we describe finite element computations of the free-surface flow of a viscous fluid down an undulating inclined plane. The technique developed here employs an orthogonal mapping that is...
An orthogonal mapping technique for the computation of a viscous free-surface flow, Int (1992)
In this paper we describe nite-element computations of the free-surface ow of a viscous uid down an undulating inclined plane. The technique developed here employs an orthogonal mapping that is...
Steady axisymmetric flows in the Taylor apparatus applying impermeable stress-free boundary conditions are computed using a finite-element technique. The unfoldings of the double singular points...
