Título da revista, periódico, livro ou evento: | Applied Sciences (Switzerland) | Volume: | 10 | Número: | 7 | Resumo: | Understanding the behaviour of suspension flows continues to be a subject of great interest considering its industrial relevance, regardless of the long time and e ort dedicated to it by the scientific and industrial communities. Information about several flow characteristics, such as flow regimen, relative velocity between phases, and spatial distribution of the phases, are essential for the development of exact models for description of processes involving pulp suspension. Among the diverse non-invasive techniques for flow characterisation that have been reported in the literature for obtaining experimental data about suspension flow in di erent processes, Electrical Tomography is one of the most interesting, since it presents perhaps the best compromise among cost, portability, and, above all, safety of handling (indeed there is no need to use radiation, which requires special care when using it). In this paper, a brief review and comparison between existing technologies for pulp suspension flow monitoring will be presented, together with their strengths and weaknesses. Emphasis is given to Electrical Tomography, because it o ers the above-mentioned compromise and thus was the strategy adopted by the authors to characterise di erent flow processes (solid–liquid, liquid–liquid, fibres, etc.). The produced portable EIT system is described, and examples of results of its use for pulp suspension flow characterisation are reported and discussed. | URI: | https://hdl.handle.net/10316/105771 | ISSN: | 2076-3417 | DOI: | 10.3390/app10072355 | Direitos: | openAccess |
