Heat exchangers have seen widespread use in aerospace applications to properly manage aircraft and propulsion system heat loads. However, these heat exchangers are typically non-conformal, costly to implement, and large in terms of their volume and weight relative to the flowrate. There is motivation therefore for heat exchangers to be better integrated into the existing flow paths of the engine, both for packaging and performance improvements. Recent advances in additive manufacturing have presented the potential to create highly conformal and better optimized heat exchangers. In this work, a reduced-order computational tool was developed to predict the thermal-hydraulic performance of an annular two-pass, cross-counterflow heat exchanger. Area ruling was used to keep the velocities nearly constant in the heat exchanger core. The outputs of the model include heat transfer rate, outlet temperature, pressure loss, heat exchanger weight and volume, and heat exchanger effectiveness as a function of the user-supplied geometry and fluid inlet conditions. Various geometries were then simulated and analyzed using the computational tool, and based on these results, a prototype heat exchanger was created using additive manufacturing for future experimental testing. Computational fluid dynamics (CFD) simulations were also performed to assess the overall accuracy of the reduced-order model.
