Estudo e aplicação de simulação computacional em problemas simples de mecânica dos fluidos e transferência de calor - Parte II: Problemas clássicos de transmissão de calor

Abstract: Dando continuidade ao estudo referenteà utilização de Dinâmica dos Fluidos Computacional (DFC) no ensino de física e engenharia, o presente trabalho visa analisar e comparar, com fins didáticos, soluções obtidas numericamente com soluções analíticas e empíricas, comumente apresentadas em sala de aula e de interesse de laboratórios de graduação, de problemas clássicos envolvendo dinâmica dos fluidos e transferência de calor. Neste estudo o foco maior foi dado a problemas de transferência de calor. Para o cálcul… Show more

“…The finite volume method (FVM) is characterized by the discretization of the system of conservation equations (mass, linear moment, energy and turbulence) in conjunction with the equations of state to obtain a system of algebraic linear equations, that are solved by means of iterative methods, obtaining a numerical result that characterizes the behavior of the flow and the heat transfer fields of a given problem. FVM is based on the integration of properties and their flows into a control volume small enough to ensure volumetric uniformity and interpolation of the properties' values between faces (ROCHA; SILVEIRA, 2012;WEHMANN et al, 2018;PATANKAR, 1980).…”

“…is already a reality that brings several benefits, such as reducing the cost and time for product development. The increasing use of computational procedures is due to the advancement of the processors' performance as well as the numerical simulation software and the decreasing costs of hardware equipment (ROCHA; SILVEIRA, 2012;WEHMANN, et al, 2018). Given that most of the flows, which are observed in the practical context of designing devices and systems, are characterized by being turbulent (VERSTEEG; MALALASEKERA, 2007), the study on the modeling of such problems is of utmost importance in the training of professionals that will work with this subject, which occurs mainly in technological and exact sciences.…”

“…A interatividade no ensino deve envoler, entre outras características, a interação física (hands-on), o emocional, intelectual e social segundo Bassoli [9], nessas categorias o aluno deve ser desafiado em seu conhecimento de tal forma que haja oportunidade de pensar e discutir, mas também seja motivado. Esta motivação pode ser obtida pela contextualização do desenvolvimento científico [10], através da interdisciplinaridade [11,12,13], e na situação de do estudo de caso, isso é alcançado quando o estudante aprende com casos próximos do real [14].…”
