Summary on Grant Application Form |
|
The structuring and interactions of the particles in electrorheological (ER) or smart fluids are to be probed by dielectric measurements when those fluids are subjected to electric and flow fields, because these interactions are the means by which such fluids become viscous and in some conditions solidify. Statistical information on such structuring would provide important information of benefit to the future development of theories on the phenomenon and further help our understanding of what makes materials effective as ER substrates. Another related issue to be addressed is the extent to which structuring is the cause of current drain in ER substrates, an important practical considerations in the application of ER. Dielectric measurements would be more generally applicable than optical techniques since most ER fluids are opaque. Also, they are appropriate because the changes in interfacial polarisation already have a theoretical basis, although it is pat of the programme to refine these. The programme could also have relevance to other practically important phenomena such as the electrical control of powder flow as well as the technologically important phenomenon of ER.
