In the end, the full 360-degree large-eddy simulation highly resolved the timeline of the combustion process, as well as the spatial resolution of the engine components represented by two billion cells. This drastically increases the size and complexity of the simulation. Instead, the simulation has to cover the entire 360 degrees of the object. вЂњIn fact, many simulations of single components compute just one of these repetitive sections,вЂќ says Dombard.Д«ut when simulating several coupled components that each possess different architectures, this is impossible.

In contrast, conventional simulations representing only one single component can benefit from the presence of repetitive elements such as the fan blades or the injectors of the combustion chamber. Within the new setup, the so-called unsteady coupling between the different components is mathematically solved and corresponds to the most realistic and high-fidelity representation of the underlying physical processes.ДЇinally, in order to represent a full engine, it was necessary to build a 360-degrees simulation. Then he developed a methodology to couple the components and achieve the fully integrated simulation. PГ©rez ArroyoвЂ™s first challenge was to perform each of the single component simulations, which exhibit a variety of different physical processes.

To carry out the simulation, DombardвЂ™s team member and postdoctoral researcher Carlos PГ©rez Arroyo used the AVBP code developed at CERFACS. вЂњWhen you couple different engine components, simulations become a lot more extensive and complex,вЂќ Dombard says. The project was done in close collaboration with two aviation companies: Safran SA, a large producer of helicopter and airplane engines, and Akira technology, a pioneering aircraft engine company that constructed the engine model DGEN380 that was simulated in this project, a so-called turbofan designed for business jets.ДЄlthough the analysis is still in progress, the first results already demonstrate that such a multi-component simulation is feasible-a fact that was not evident before-and that it delivers significant benefits. JГ©rГґme Dombard, together with their co-workers at CERFACS, a private laboratory in Toulouse, France, have successfully performed one of the first ever full-engine simulations.Д®xecuted on PRACE supercomputers, the simulation included three engine components: the fan, the high-pressure compressor, and the combustion chamber. Carlos PГ©rez Arroyo and project leader Dr. ThatвЂ™s why, so far, simulations have mostly consisted of only one engine component, such as the high-pressure compressor or the combustion chamber.Д«ut now, Dr. However, engine simulations that make use of supercomputers have also been limited due to the vast computing power required to perform detailed and accurate simulations. Computer simulations play an essential role in this process, expanding and enhancing experimental results by adding information that is difficult to gain from experimental setups. ThatвЂ™s why engineers and scientists are continuously working to improve aircraft engine designs.

After all, more efficient engines require less fuel, which reduces cost and atmospheric pollution.

But their complex machinery could still be optimized for greater efficiency. New methodology couples components and represents a full 360-degree simulationДЄirplane engines work, no question about it.Previous simulations were limited to single components due to demands on computing power.Simulations of aircraft engines are key to improving efficiency and reducing pollution.
