Brief Description of Current Research
Professor David Boger’s contributions to fundamental research in fluid
mechanics are highlighted by a class of fluids which now bear his name globally
– Boger Fluids. These fluids are constant-viscosity elastic
(non-Newtonian) fluids that behave as both liquids and solids. The detailed
experimental investigations using such materials to define fluid elasticity
effects in important flows, the linking of basic surface chemistry to the
continuum properties and processing of particulate fluids and the development of
novel methods for flow property measurement have resulted in significant
industrial outcomes in the petroleum, food, polymer and minerals industries.
The best known application of this research in Austarlia was solving the
problem of disposing of ‘red mud’ (the waste product of the processing of
bauxite to alumina), which was pivotal to developing environmentally acceptable
processes for mining the low-grade bauxite in Western Australia. In addition to
the financial benefits to the alumina industry, the work has been recognised by
a series of national and international awards for its contribution to
environmental management. There is a major activity in exploiting rheology for
waste minimisation in the minerals industry.
Another major achievement resulting from Professor Boger’s research has been
the development of a methodology by which the fluidity of high wax content crude
oils is maintained for unimpeded pipeline transportation, providing significant
financial gains to the oil industry.
Professor Boger’s fundamental work on non-Newtonian fluids has application
also to the behaviour of drops of fluids. His recent research is linked to
applications in atomisation, inkjet printing, delivery of agricultural
chemicals, and with intelligent gels. In addition, fluid flow has become an
important component of nanotechnology, offering new horizons for Boger Fluids.
His current interest is in sustainability, rheology and the triple bottom line.
Professor Boger has been awarded numerous prizes for his research including
the Annual Award of the British Society of Rheology in 1983 for notable
contributions to rheology, and the 1995 Walter Ahlström Environmental Prize
awarded annually by the Finnish Academies of Technology in recognition of
significant technological achievements which advance industrial applications
using energy and raw materials. He is a Fellow of the Learned Academies of
Science and of Technological Sciences and Engineering. In 2003, Professor
Boger received the Clunies Ross National Science and Technology Award,
following from the Chemeca Medal of the Institution of Chemical Engineers
and the Flinders Medal of the Australian Academy of Science in 2000, and
the Victoria Prize in 2002. In 2004, Professor Boger received the
British Society of Rheology Gold Medal, its highest award.
