B01 is dedicated to the investigation of fundamental effects and sensitivities coupled to the functional integration of heat transferring structures for improved waste heat transfer in highly integrated propulsion systems. The high amount of heat that has to be transferred into the propulsor annulus within the given spatial boundaries lead to heat transfer intensification with micro structured surfaces. The additional pressure drop of these micro structures and their time dependent behaviour in terms of fouling due to particle laden flows shall be investigated in this project. This will be accomplished by simplified experiments and scale resolving numerical calculations. The result is a surrogate model that will be exchanged within Syntrac.

The higher weight of novel energy storage solutions in aircraft call for a higher lightweight potential as well as load-path oriented orthotropic design options. Furthermore, new functionalities such as optimised heat distribution zones are also required. Hence, the project C01 will examine the potential of structure-integrated thermal management by using hybrid laminates with continuous (fibre reinforced polymers doped with graphene materials) and discrete (fibre metal laminates, hybridisation) functionalisation. The investigations will include experimental and numerical methods that are suitable to design and validate dedicated intra- and interlaminar heat flux paths of these composite materials with realistic boundary conditions e.g. for the known thermal convection in a dedicated test chamber.

Project C02 considers porous media as a promising technology for various applications such as exhaust gas treatment and waste heat recovery for integration into different aircraft configurations. A key physical cross-scale aspect here is condensation from the vapor phase and the removal of the condensate. Understanding the connection between the microscopic processes and their macroscopic effect is essential to the successful exploitation of porous media. To achieve this goal, we combine complementary experimental and numerical methods in this project.
