Developments in aircraft engines should go hand in hand with advanced technologies that aim to reduce aviation impact on citizens and the environment. EU-funded scientists developed critical new tools for optimising engine combustion systems for green and sustainable air transport.
The fuel injector is critical to the design of low-emission combustors. By understanding and controlling the complex physics of fuel atomisation, there is great potential for minimising harmful emissions. Until now, simulations have been relying on over-simplistic definitions of the fuel spray. In addition, current soot models are not sufficiently accurate to support the design of new environmentally friendly combustors. The two modelling areas are closely related as the spray characteristics set the boundary conditions for soot modelling.
