Resumo: | The particle cyclic and orderly movement inside a spouted bed has as main advantages of this technique, thus enabling an effective particle-particle and fluid-particle contact, which results in high transfer rates of heat, mass and movement. Due to their intrinsic characteristics, spouted beds have been widely used in industrial processes, however, there are some disadvantages operation inherent, the most complex of which are related to the segregation phenomenon, which occurs due to the multicomponent mixtures use in production lines, causing a non-uniform product formation, which compromises the equipment performance. In this way, a better understanding of the segregation phenomenon inside a spouted bed, is of fundamental importance for its design, operation and optimization. In the present work, a non-intrusive methodology using a solidification-slicing approach was used for the investigation of radial and axial segregation behavior in a spouted bed. The effects of diameter, density, and shape of the particles, as well as the initial particle loading, and the inlet air velocity, on segregation were qualitatively and quantitatively assessed. Regarding the results, binary mixtures with aspect, diameter and density ratios, equals a 2.0, 2.0, and 1.9, respectively, show a random mixture condition. Binary mixtures with diameter ratio of 4.5 and density ratio of 5.8, show radial and axial segregation. As regards to radial segregation, the higher or denser particles, tended to form a central core at the spout region, and the smaller or lighter particles, flowed to the annular region near the spouted bed wall. The particle dynamics seemed not to be significantly affected by changing the particle initial loadings in systems with aspect ratio of 2.0 and density ratio of 5.8, however, affected systems with diameter ratio of 4.5. As expected, the increase in diameter and density ratios caused an increase in radial and axial segregation. The segregation phenomenon for binary mixtures with high density ratio, were shown to be dependent of the initial particle loading configuration, but independent of the superficial gas velocity. |

Devido a estas características, o leito de jorro é vastamente utilizado em processos industriais. Apesar disto, algumas desvantagens são inerentes à sua operação, sendo a mais complexas delas, correlacionadas ao fenômeno de segregação, que ocorre devido a utilização de misturas multicomponentes em linhas produção, provocando a formação de um produto não uniforme, o que, compromete a performance do equipamento. Desta forma, um melhor entendimento do fenômeno de segregação no interior de um leito de jorro, se mostra de fundamental importância para o seu projeto, operação e otimização. No presente trabalho, uma técnica não-intrusiva de gelificação e corte do leito de partículas, foi utilizada no estudo do comportamento da segregação radial e axial em um leito de jorro. Os efeitos do diâmetro, densidade e forma das partículas, assim como também, a análise da velocidade de fluido de arraste na entrada do equipamento e a distribuição inicial do sistema particulado, foram analisados de forma qualitativa e quantitativa. Com relação aos resultados, as misturas binárias com razões de forma, diâmetro e densidade, iguais a 2,0, 2,0 e 1,9 respectivamente, apresentaram uma mistura final randômica. Misturas binárias com razões de diâmetro de 4,5 e de densidade igual a 5,8, apresentaram segregação radial e axial. No que se refere à segregação radial, as partículas de maior diâmetro ou densidade, se concentraram na região central do leito, enquanto, as partículas menores ou mais leves, se concentraram na região anular. A distribuição inicial do sistema particulado não afetou misturas binárias com razão de aspecto igual a 2,0 e razão de densidade de 5,8, porém, afetou sistemas com razão de diâmetro igual a 4,5. Como era esperado, o aumento das razões de diâmetro e densidade provocaram o aumento da segregação radial e axial. A distribuição inicial do sistema particulado, afetou a dinâmica das partículas no interior do leito de jorro, em misturas binárias que possuem altas razões de diâmetro, onde o aumento da velocidade superficial de gás não provocou mudanças no comportamento segregativo da mistura.Submitted by Marlene Santos (marlene.bc.ufg@gmail.com) on 2020-02-26T17:37:32Z No. of bitstreams: 2 Dissertação - Jéssika Nayara Santos Morais - 2020.pdf: 6098880 bytes, checksum: 7906b3cf63902ed06d631d8cf378e9ee (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2020-02-27T11:04:34Z (GMT) No. of bitstreams: 2 Dissertação - Jéssika Nayara Santos Morais - 2020.pdf: 6098880 bytes, checksum: 7906b3cf63902ed06d631d8cf378e9ee (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2020-02-27T11:04:35Z (GMT).
