Abstract

This paper aims at investigating the effect of upstream turbulence (for instance coming from the engine’s internal geometry) on the jet flow development. Simulations are performed using ZDES [4] combined with synthetic turbulence generation methods. Two cases are studied: an incompressible, single-stream jet and a compressible dual-stream one. It is shown that the upstream turbulence reduces the RANS-to-LES transition and improves the prediction of the location of the shock-cells and global jet flow development, which advocates a systematic consideration of realistic nozzle exit conditions in eddy-resolving simulations.
