| Description | New results on flow of thickening dispersions in complex flows such as squeezing, relaxaing, coating, pipe flows. Often cause of major headaches in processing, high solids content dispersions do not typically flow like simple controllable liquids. Our results extend the range of flows of practical importance where we are begi9nning to understand how to treat and control the flow of such 'difficult' materials. |
| Exploitation Route | Major users are involved in the research project - prediction of flow and design of materials Industries such as foods, ceramics, paints, nanoengineering, pharmaceuticals, oil and gas |
| Sectors | Agriculture, Food and Drink,Chemicals,Construction,Education,Electronics,Energy,Environment,Manufacturing, including Industrial Biotechology,Pharmaceuticals and Medical Biotechnology |
| Description | Major impact so far is in engagement with public and schools around the research themes and challenges for these 'everyday' materials. Some of these are detailed elsewhere in the fish but it is worth mentioning these here as this is a major and broad aim of the research that goes beyond the academic and industrial goals. This impact continues with sustained engagement with schools including mentoring projects focussed on children in traditionally 'low attainment' schools as recognised by indicies of deprivation in Scotland. After the close of the project our engagement activities continue and have been infromed by our research results. We are beginning to see an impact on the number of admissions to UG degrees from normally less well represented cohorts such as SIMD areas in Scotland, which we can partly attribute to the engagemtn work associated with this project. Additional impact is the completion of a related PhD project with a draft publication to be submitted. This has also led to the design of a simple, cheap 'bespoke' apparatus, constructred using hobby-level 3d printing, that would be suitable for use in teaching laboratories in schools, physics, engineering etc departments which will be the subject of a publication. |

| Title | Predictive formulation of high-solid content complex dispersions (EPSRC Project EP/N024982/1) |
| Description | Full dataset from EPSRC project (09/16-10/19) 'Predictive formulation of high solid-content complex dispersions'. Data represents rheological measurements under various conditions of flow: Shear flow - as measured in DHR rheometer: all in folder 'Shear Data' and subfolders Squeeze flow - as measured in DHR rheometer and Anton Paar rheometer: all in folder 'squeeze flow data' Creep and relaxation tests - as measured in Haake Caber: all in folder 'squeeze flow data'/subfolder 'creep and relaxation tests'. Data is represented in xlsx format. Some 'raw data' is in .cbr Caber proprietary format but is all represented in the xlsx compiled/analysed data files. Materials: the majority of work is on cornstarch suspensions in glycerol/water mixed solvent, as indicated by subfolder and file nomenclature. There is some base data using pure glycerol for testing: in folder 'squeeze flow data'/subfolder 'glycerol'. The majority of data are in xlsx (Excel) format or in opj (Origin Project) format. Open source/free readers are available for these formats although further analysis and editing would require the full software versions. There are some additional representations of results in pdf and pptx formats. The above info is also available in a readme file. |
