Abstract
Understanding the heat transfer phenomenon through geometry with insertion of other elements is a concept of disturbing questions. The work accomplished proposes propositions that come to the encounter of these questions when evaluating thermally the influence of inclusions of air in an aluminum alloy 6351 T6. The test bodies used in this work may be associated with composite materials due to the composition of two phases in their geometry. Such materials have been widely used in industry because of their beneficial properties that are potentiated giving a higher yield to the work employed. In order to obtain the largest number of data, four pieces were made in which analyzes were performed using the finite element method, executed in ANSYS software and an experimental evaluation performed in an apparatus manufactured according to the needs found, the results were submitted to statistical analyzes to prove their veracity. Analyzing the temperatures found in the test, it is possible to identify that the difference in size of the air inclusions and their geometric distribution has significant interference in what involves heat transfer. This work may contribute to future studies on heat transfer in porous structures or in geometries with inclusions of other materials.
