Background and motivation
Additive manufacturing (AM) offers great potential for the simple and direct production of complex and functional components made of polymers and metals. In power bed fusion (PBF), three-dimensional components are built up layer by layer. This reduces the complexity of a three-dimensional body to be manufactured to a multitude of two-dimensional manufacturing steps and enables the implementation of very complex structures. Due to the freedom of design, PBF offers great innovation potential compared to conventional manufacturing processes. In many cases, component designs that exploit the possibilities of AM show higher technical performance or functionality compared to components manufactured by conventional processes. Previous works on additively manufactured heat exchangers (AM HXs) showed that heat transfer improvements and pressure loss reductions are possible through the use of AM and an associated complex geometry of fluid-fluid heat exchangers (HXs). In aerospace technology, gas‑liquid heat exchangers are of interest for numerous applications. This student work’s goal is to use numerical analysis to compare core structures for gas-liquid heat exchangers. Existing core structures are to be investigated and design guidelines for AM heat exchanger core structures of high efficiency are to be developed.
