ALESIA - Advanced Large Eddy Simulation In Aeroengines

Project: Research project

Project Details


The digital aeroengine of the future allows the design, the prediction of efficiency as well as of the operational behavior through massive computer simulation without the need for additional experiments. In order to achieve this goal, the flow in aeroengines has to be predicted with innovative and more reliable methods. The flow in aeroengines is always transient and also highly turbulent. The accurate simulation of the unsteady turbulent flow under consideration of the laminar-to-turbulent transition in the boundary layer is therefore a prerequisite for the design of modern aeroengines. In the industrial design process, the Reynolds-averaged Navier-Stokes equations (RANS approach) are usually applied which consider the turbulence and transition by appropriate models. But this computationally effective approach often suffers from the poor quality of the applied models. Therefore, the goal of the project ALESIA is the improvement of the simulation of turbulent aeroengine flows by the application of Large Eddy Simulation (LES) to come closer to the ultimate goal of the digital aeroengine.
