Large-eddy simulation in aero applications; wall modeling, robustness, accuracy and efficiency

Research Project, 2024 – 2028

The project purpose is to build up a flow simulation capability based on large eddy simulation (LES) for an industrial aeronautical context. The aim is an overall capability where accuracy, efficiency and robustness is taken into account. The project will study inovative wall modelling, including machine learning mehtods. Methods for improved numerical accuracy will be explored with the aim to meet industrial requirements. Moreover, studies will be perfomed to execute LES on graphics processing units (GPU) with the aim to meet industrial goals for efficiency and shorter lead times.

The expected result is a LES methodsology that meets the requirements on accuracy, efficiency and robustness based on an industrial aeronautical perspective. The expected effect due to the project is an improved applicability of LES for aeronautical applications and thereby a contribution to the development of next generation of aircraft. Moreover, the project is expected to contribute to strengthen national and international collaborations as well as dissimination of knowledge and capabilities through publications, workshops and people bridging between industry/academia.
