dc.description.abstractThe development of aero engines with geared fans may require the use of a heat exchanger system embedded within the bypass duct to dissipate heat due to the losses within the power gearbox of the fan. It is pertinent that the naturally ventilated heat exchanger system (HEX) is designed and installed to minimise detrimental impacts on the performance of the engine while meeting the HEX heat transfer requirements. This paper demonstrates the capabilities of a coupled mixed fidelity method to model a ventilated HEX embedded within the bypass duct. A systematic approach is presented to quantify the sensitivity of HEX heat transfer, HEX volume and engine net thrust to perturbation in HEX overall size and integration. A method to explore and quantify the trade-offs in HEX performance and bypass performance is detailed. The method can be used to allow rapid assessment of the integration of the HEX with the bypass duct.en_UK
