Assessment of Additive Manufacturing Limits for Eco-Design Optimization in Heat Exchangers - AManECO
Selective Laser Melting (SLM) is key for improved design and production processes of aviation parts. Applied to heat exchangers (HX), it could dramatically improve global eco efficiency through access to radically new designs and open horizons in terms of shape, weight and efficiency. Nevertheless, some problems need to be solved regarding capability of Additive Manufacturing (AM) to manufacture thin walls, small holes/gaps, low overhang angles, resulting surface roughness and mechanical strength. AManECO aims to enhance knowledge of metal AM and, specifically, the capability of the SLM process to manufacture thin layers and wall thicknesses with adequate surface finish using AlSi7Mg0.6 and INCO 718 materials. In particular, to investigate aerothermal and mechanical performance of thin walls, to predict them in the design of AM-HXs and consequently, be able to optimize the HX´s design process in an eco-friendly way after knowing the limits of the metal AM technology. For this purpose, testing samples will be designed and manufactured to be then characterized in terms of surface properties, pressure resistance and gas tightness evaluation, equivalent stiffness and aerothermal properties. Besides, numerical studies based on FEM and CFD simulations will be done. Then, a representative design of HX based on the initial SOA of AM limitations will be optimized with the gained knowledge. These designs, before and after optimization, will be produced and characterized. Then, a Life Cycle Inventory (LCI) database will be created to evaluate the ECO potential of the innovative HX.
