Resumo: | Although, studies are being carried out, the determination of the magnitude and distribution of pressure during unloading still presents considerable difficulties, because it is a complex phenomenon in which the pressures depend, among other things and the way the stored material flows. So, the present work using four food products in powder form, and employs the equations given in the standard BS EN 1991/4 (2006) to determine the Asymptote distribution representative of pressures along the body of the silo which features 8 meters high and 2 meters in diameter. This silo, made with smooth steel plates with concentric hopper with inclination of 60° with the horizontal. The flow properties were determined using the Jenike Shear Cell. A similar result was obtained from the pressures between the products cornstarch and potato starch by similarity in particle size. The products under review are cohesive and present no easy flow, however, in none of the cases the pressures of friction along the wall have distinguished themselves between charge and discharge. |

Así, el presente trabajo emplea las ecuaciones presentadas en bs EN 1991/4 (2006) para determinar el asisto representativo de la distribución de presiones a lo largo del cuerpo del silo que tiene 8 metros de altura y 2 metros de diámetro efectivo posible para almacenar 4 productos alimenticios en polvo, e. Este silo, hecho con placas planas de acero, equipado con tremonha concéntrica con inclinación de 60 ° con horizontal. Las propiedades de flujo se determinaron utilizando Jenike Shear Cell. Se obtuvo un resultado similar de las presiones entre el almidón de maíz y la fécula de patata porque presentaban similitud en la granulometría. Los productos en estudio son cohesivos y no presentan un flujo fácil, sin embargo, en ninguno de los casos las presiones de fricción a lo largo de la pared se distinguieron entre carga y descarga. Embora, estudos estejam sendo realizados, a determinação da magnitude e distribuição das pressões durante a descarga ainda apresenta dificuldades consideráveis, uma vez que se trata de um fenômeno complexo em que as pressões dependem, entre outras coisas e da maneira como o material armazenado flui. Sendo assim, o presente trabalho emprega as equações apresentadas na norma BS EN 1991/4 (2006) para determinar a assíntota representativa da distribuição das pressões ao longo do corpo do silo que apresenta 8 metros de altura e 2 metros de diâmetro efetivo possível de armazenar 4 produtos alimentícios pulverulentos, e. Silo este, confeccionado com chapas de aço liso, munido de tremonha concêntrica com inclinação de 60° com a horizontal. As propriedades de fluxo foram determinadas utilizando o Jenike Shear Cell. Obteve-se resultado semelhante das pressões entre os produtos amido de milho e a fécula de batata por apresentarem similaridade na granulometria. Os produtos em estudo são coesivos e não apresentam fluxo fácil, porém, em nenhum dos casos as pressões de atrito ao longo da parede se distinguiram entre o carregamento e o descarregamento.Research, Society and Development2021-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2080610.33448/rsd-v10i12.20806Research, Society and Development; Vol. 10 No. 12; e532101220806Research, Society and Development; Vol. 10 Núm. 12; e532101220806Research, Society and Development; v. 10 n. 12; e5321012208062525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/20806/18512Copyright (c) 2021 Diego José Araújo Bandeira; Ariadne Soares Meira; Patricio Gomes Leite; Márcia Janiele Nunes da Cunha Lima; Antônio Nunes de Oliveira; Rodolfo Ramos Castelo Branco; Keviane Pereira Aragão; Anúbes Pereira de Castrohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBandeira, Diego José Araújo Meira, Ariadne SoaresLeite, Patricio GomesLima, Márcia Janiele Nunes da Cunha Oliveira, Antônio Nunes de Branco, Rodolfo Ramos Castelo Aragão, Keviane PereiraCastro, Anúbes Pereira de2021-11-14T20:26:51Zoai:ojs.pkp.sfu.ca:article/20806Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:40:20.937024Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
