Análise de troca térmica em trocador de calor de tubos concêntricos concorrente mediante diferentes configurações de aletas

Abstract

In the present study the computational simulation was performed in Ansys CFX of a double tube type heat exchanger, observing a heat transfer by convection with a parallel flow, through geometries with a different kind of fins, being of the annular, conical and vertical plate’s type. A comparative chart presented is, allowing you to compare and understand which type of fin is better, depending on the industry's objective. The heat exchanger with annular fins had the highest thermal exchange and the highest charge loss. When choosing the heat exchanger should be taken into account for the one that presents the best performance with the lowest cost in view of the design and operation conditions.
