Resumo: In this study, we present an immersed boundary method to analyze interactions between fluids and bodies in two-dimensional (2D) flows around complex geometries, focusing on heat transfer and turbulence. The method uses an Eulerian grid for the fluid, and another Lagrangian grid for the immersed body, ensuring conditions of no slip and considering heat exchanges. We use Navier-Stokes and energy equations with Smagorinsky (LES) and Spalart-Allmaras (URANS) turbulence models. A computational code was implemented to calculate lift, drag and Nusselt coefficients, comparing the results with previous studies at different Reynolds numbers. This research advances the understanding of fluid-body interactions in complex geometries and thermofluid dynamics.

El método utiliza una malla euleriana para el fluido y otra lagrangiana para el cuerpo sumergido, asegurando condiciones de no deslizamiento y considerando los intercambios de calor. Utilizamos ecuaciones de energía y de Navier-Stokes con modelos de turbulencia de Smagorinsky (LES) y Spalart-Allmaras (URANS). Se implementó un código computacional para calcular los coeficientes de sustentación, resistencia y Nusselt, comparando los resultados con estudios previos con diferentes números de Reynolds. Esta investigación avanza en la comprensión de las interacciones fluido-cuerpo en geometrías complejas y dinámica de termofluidos.Neste estudo, apresentamos um método de fronteira imersa para analisar interações entre fluidos e corpos em escoamentos bidimensionais (2D) em torno de geometrias complexas, com foco na transferência de calor e turbulência. O método utiliza uma malha Euleriana para o fluido, e outra malha Lagrangiana para o corpo imerso, assegurando condições de ausência de deslizamento e considerando trocas de calor. Usamos equações de Navier-Stokes e da energia com modelos de turbulência Smagorinsky (LES) e Spalart-Allmaras (URANS). Um código computacional foi implementado para calcular coeficientes de sustentação, arrasto e Nusselt, comparando os resultados com estudos anteriores em diferentes números de Reynolds. Essa pesquisa avança na compreensão das interações fluido-corpo em geometrias complexas e na termofluidodinâmica.Universidade Federal de Viçosa - UFV2023-10-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1666410.18540/jcecvl9iss11pp16664-01eThe Journal of Engineering and Exact Sciences; Vol. 9 No. 11 (2023); 16664-01eThe Journal of Engineering and Exact Sciences; Vol. 9 Núm. 11 (2023); 16664-01eThe Journal of Engineering and Exact Sciences; v. 9 n. 11 (2023); 16664-01e2527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/16664/8274Copyright (c) 2023 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos, Rômulo Damasclin Chaves dosSales, Jorge Henrique de Oliveira2024-03-26T17:20:57Zoai:ojs.periodicos.ufv.br:article/16664Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2024-03-26T17:20:57The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
