Additive Manufacturing (AM) reduces the time between concept generation and manufacture by creating complex structures that can more efficiently use space compared to traditional manufacturing. This project allowed us to design a high temperature heat exchanger that could be used with a micro gas turbine system, with AM serving to integrate these traditionally separate parts into one component. Using Computational Fluid Dynamics (CFD) and High Performance Computing (HPC) we created a competitive advantage. By arriving at a high value outcomes quickly and cost effectively, and by helping to analyse the behaviour of new products under development through faster, more-informed decision-making, greater insight and more robust feedback is incorporated into the design cycle.
