Summary on Grant Application Form
The work will address both theoretical and experimental aspects of the basic particle science, technology of particle systems and engineering of desired material properties in very highly concentrated particulate soft solids (pastes). Direct measurement of normal and shear nanorheology of inorganic particles and surfaces with adsorbed organics, controlled pH and presence of small ions will provide fundamental interaction laws for distinct element simulations using research code provided by Cambridge University. The results of these simulations will be combined with direct measurements on aggregates of inorganic particles to formulate a structural characterisation for pastes in terms of large flow units or aggregates with complex internal mechanical properties. These flow units will in turn form the basis for discrete element simulations using specialised commercial code (Eulerian/Lagrangain finite/discrete element). A parallel line of research will be followed using deformable gel particles as a model system. The formation of structure during flow will be studied directly using confocal microscopy and MRI measurements and interpreted with the aid of boundary element calculations and phenomenological (diffusive and multiphase transport) models. The combined results of all the studies will be distilled into concise models and compared with measurements of bulk and wall continuum mechanical properties of pastes.
