Abstract
This study explores the feasibility of using fuel as working fluid in a surface heat exchanger based on the Boeing wing's geometry of 777-300ER. Through Computational Fluid Dynamics (CFD) simulations, two geometric configurations—parallel and serpentine—were evaluated under various operational conditions, including aircraft on the ground (AOG) and in cruise flight. The results indicate that the serpentine configuration achieves higher heat exchange rates, but requires higher inlet pressures. Conversely, the parallel configuration, while less effective in heat exchange, offers a simpler and potentially lighter solution. Higher mass flow rates were found to enhance heat transfer but reduced the cooling efficiency due to decreased fuel residence time in the heat exchanger.
