Resumo: The spouted bed is an equipment highly influenced by the porosity of the static bed. Thus, this work aimed to employ literature correlations and the discrete element method to simulate the packing of monoparticle beds and binary mixtures of 1 and 4 mm spheres. The experimental minimum porosity was 0.267, and the Dias correlation agreed well with experimental data and was able to distinguish the occupation and filling packing regimes adequately. Regarding the simulations using the Discrete Element Method, the parameters calibration of the Hertz-Mindlin contact force model showed that the particle-particle static friction coefficient is the factor that most influences the packing, followed by the particle-to-particle friction coefficient bearing friction coefficient, while the particle-to-wall bearing friction coefficient did not influence the bed voidage. The simulations adequately represented the transition between the occupation and filling regimes that govern packing.

Por lo tanto, este trabajo tuvo como objetivo emplear correlaciones de la literatura y el método de elementos discretos para simular el empaquetamiento de lechos de monopartículas y mezclas binarias de esferas de 1 y 4 mm. La porosidad mínima experimental fue 0.267, y la correlación Dias fue la más cercana al valor experimental y fue capaz de distinguir adecuadamente los regímenes de empaquetamiento de ocupación y llenado. En cuanto a las simulaciones que utilizan el Método de Elementos Discretos, la calibración de los parámetros del modelo de fuerza de contacto de Hertz-Mindlin mostró que el coeficiente de fricción estática partícula-partícula es la variable que más influye en la operación de empaque, seguido del coeficiente de fricción del rodamiento partícula-partícula, mientras que el coeficiente de fricción del rodamiento de partícula-pared no influyó en la porosidad del lecho. Las simulaciones representaron adecuadamente la transición entre los regímenes de ocupación y llenado que rigen el empaque.O leito de jorro é um equipamento altamente influenciado pela porosidade do leito estático. Assim, este trabalho teve o objetivo de empregar correlações da literatura e o método de elementos discretos na simulação do empacotamento de leitos de monopartículas e misturas binárias de esferas de 1 e 4 mm. A porosidade mínima experimental foi 0,267, sendo que a correlação de Dias foi a que mais se aproximou do valor experimental e que conseguiu distinguir adequadamente os regimes de empacotamento de ocupação e preenchimento. Quanto às simulações empregando o Método de Elementos Discretos, a calibração dos parâmetros do modelo de força de contato de Hertz-Mindlin mostrou que o coeficiente de atrito estático partícula-partícula é a variável que mais influencia a operação de empacotamento, seguido pelo coeficiente de atrito de rolamento partícula-partícula, enquanto o coeficiente de atrito de rolamento partícula-parede não influenciou a porosidade do leito. As simulações representaram adequadamente a transição entre os regimes de ocupação e enchimento que regem o empacotamento.Research, Society and Development2021-08-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1901210.33448/rsd-v10i10.19012Research, Society and Development; Vol. 10 No. 10; e553101019012Research, Society and Development; Vol. 10 Núm. 10; e553101019012Research, Society and Development; v. 10 n. 10; e5531010190122525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/19012/17142Copyright (c) 2021 Daiane Bortolote Ferreira; Ricardo Correa de Santana; Marcos Antônio de Sousa Barrozo; Davi Leonardo de Souza; José Luiz Vieira Neto; Kassia Graciele dos Santoshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFerreira, Daiane BortoloteSantana, Ricardo Correa deBarrozo, Marcos Antônio de SousaSouza, Davi Leonardo deVieira Neto, José Luiz Santos, Kassia Graciele dos2021-10-02T21:49:16Zoai:ojs.pkp.sfu.ca:article/19012Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:39:00.579206Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
