Análise numérico-experimental da agitação de calda em reservatórios de pulverizadores agrícolas

Abstract: RESUMO:Neste trabalho apresenta-se um estudo numérico-experimental do comportamento da agitação de fluido em reservatórios de pulverizadores agrícolas. Uma adequada agitação da calda de defensivos agrícolas em um reservatório é muito importante para garantir a ho mogeneidade da pulverização ao longo de toda a cultura. O objetivo do estudo foi avaliar a viabilidade da utilização de um modelo computacional aplicado ao problema de agitação de calda em reservatórios de pulverizadores agrícolas, e assim, auxiliar n… Show more

“…The results of the numerical and experimental comparison of the air distribution system in the test bench with A1 and B1 radial fans need to be evaluated for the values of the dimensionless Yplus (dimensionless distance relative to the wall and used as information on the mesh resolution) throughout the air distribution system to ensure that the results close to the wall are valid. In this study, Yplus must be lower than 300 for the k-Epsilon model (Micheli et al, 2015).…”
