Fureby C.; 2022, “Paving the Route Towards Green Aviation with Hydrogen and Biojetfuels – A Numerical Study using OpenFOAM”, OpenFOAM and combustion Webinar 2022-11-25, SNU, Singapore.
Abstract: Aviation is at the crossroads: Before the Covid-19 pandemic we were struggling with crowded flight corridors across Europe, in Asia and in the Americas, as well between the different continents in parallel to trying to mitigate the climate impact of aviation. The future of aviation is likely to include a range of technologies trying to mitigate these challenges. Regarding the climate impact of aviation, all-electric aircraft, conventional aircraft running on alternative or bio jet fuels, and cryoplanes have all been proposed as potential solutions. Regarding the crowded flight corridors potential solutions include shifting long-haul flights from intercontinental to antipodal trajectories, requiring different types of aircraft potentially based on supersonic or even hypersonic design burning hydrogen or bio jet fuels. The European Commission currently funds several research projects advancing these areas, including STRATOFLY, MORE&LESS, MYTHOS, and NEUMANN, whereas Sweden has recently started several competence centers and among them CESTAP focusing on sustainable turbine fuels and their utilization. In this lecture I will discuss the background for developing these projects in Europe and some of the technological solutions that we need to develop. More specifically, I will focus on the engine technologies required to reach these goals, and particularly on the combustion processes required to deal with the wider spectrum of fuels and operating conditions involved in developing new engine technologies. High-fidelity experiments and numerical simulation are cornerstones in the technology development that can both mutually validate each other and, at the same time, provide unique information about the physics and chemistry involved. Examples from studies conducted several of the aforementioned projects will be discussed.
