Abstract
Devido à grande utilização em processos industriais, geração de energia térmica e em refinarias, trocadores de calor sempre despertaram o interesse de pesquisadores, seja nas universidades ou na própria indústria. Interessados em desenvolver projetos mais eficazes e seguros, muito esforço tem sido empregado tanto em soluções computacionais, simulações numéricas, quanto em trabalhos experimentais. Esse artigo apresenta uma ferramenta computacional desenvolvida para fornecer parâmetros que possibilitam o dimensionamento de um trocador de calor casco e tubo. Utilizando os métodos da Diferença de Temperatura Média Logarítmica e NUT, o programa desenvolvido em Excel fornece a área necessária para a troca de calor dadas as condições de processo. Os resultados obtidos com o programa foram comparados com um resultado da bancada de trocador de calor da UPM.
Due to the wide use in industrial processes, thermal energy generation and in refineries, heat exchangers have always aroused the interest of researchers, whether in universities or in the industry itself. Interested in developing more effective and safe projects, a lot of effort has been used both in computational solutions, numerical simulations, and in experimental work. This article presents a computational tool developed to provide parameters that enable the design of a shell and tube heat exchanger. Using the Average Logarithmic Temperature Difference and NUT methods, the program developed in Excel provides the necessary area for heat exchange given the process conditions. The results obtained with the program were compared with a result from the UPM heat exchanger bench.
