Improved ejector models for higher-performance engines
The EU-funded EJEMOD project will set up and run steady-state and transient experiments and computational fluid dynamics simulations of different ejector geometries. Based on the generated data, the project will then develop and validate new 0D/1D on the Dymola platform. Steady-state models will describe on-design and off-design modes thermal performance. Transient models will be used to optimise the system control, through the analysis of the transitions between two operating points or during transitions towards abnormal functioning. Surrogate modelling methodologies based on deep learning will also be used as a complementary approach. Such robust 0D/1D models covering the full operating envelope will allow future optimisation of the ejector implementation in the aircraft bleed-air system, improving the net performance of the engine.
