Utilização do MS Excel e do DWSIM como ferramentas computacionais no dimensionamento de trocador de calor casca e tubo

Abstract

Heat exchangers are equipment used on heating and cooling of products or environments. A view of the concepts involved in the processes of thermal exchange, as well as the sizing of equipment for this unitary operation, must be understood in a clear and objective way within the course of chemical engineering, enabling an understanding of the relationship between the variables and their respective influences in a chemical process. The use of computational software that simulate processes appears as a powerful teaching tool within this context. In this work, two software were used: Excel and DWSIM, compared to an analytical method in order to solve a theoretical problem involving the design of a heat exchanger. Among the methods studied, MS Excel presented the best results. The objective of this work was to demonstrate teaching strategy with the use of a computer software tool of easy access, with a friendly and accessible graphical interface, in solving problems of chemical engineering.
