Abstract
This thesis project undertakes a comprehensive numerical analysis of aerodynamic cooling ducts in the context of fuel-cell powered aircraft, aiming to enhance the efficiency and performance of these innovative propulsion systems. The use of fuel cells in aviation presents a paradigm shift towards sustainable and environmentally friendly air travel. However, the integration of fuel cells introduces new challenges, particularly in managing the excess heat generated during operation. Aerodynamic cooling ducts play a crucial role in dissipating this heat while minimising aerodynamic drag.
The numerical analysis involves the application of aerodynamics, thermal management and performance techniques to model and simulate the complex airflow within the cooling ducts. Parameters such as duct geometry, airflow properties, and heat transfer rates are systematically investigated to optimise the cooling process. The study also explores the interaction between the cooling ducts and the overall performance of the aircraft, considering the impact on drag and fuel efficiency.
