Summary on Grant Application Form |

The proposal seeks to develop MRI and MR techniques so as to provide a tomographic ability to investigate structure-processing variations in-situ, for a variety of soft solids and pastes. It intends to exploit the wide range of techniques available within MRI/MR to differentiate between different phases, as well as the ability of MRI to produce 2D or 3D visualisations of velocity, thus providing shear and elongational flow fields. Initially this will be done in a variety of rheological measurement devices, adapted to be compatible with the MRI equipment (Rheo-NMR devices). Similar measurements will then be acquired under typical processing conditions as provided by extrusion and injection moulding apparatus. Interpretation of this data will be aided by the corresponding measurements in the Rheo-NMR devices. The materials to be investigated include a variety of commercial soaps and a fish-feed paste which is extruded into pellets. Whilst pursuing the development of MRI as a tomographic tool to describe the structure-processing relationships in these materials, several industrially relevant problems will be addressed. Methodologies to exert control over the distribution of either cracks, silicone oil or perfume capsules in the soap material and pore structure in the fish-feed paste will be investigated.
