Abstract

The study presented in this paper is motivated by the increasing need of high fidelity data for aircrafts in off-design conditions. The behaviour of turbulent structures computed using the Zonal Detached Eddy Simulation (ZDES) approach when they come through a chimera interface is investigated. Three different chimera (or overset) are compared to a reference ZDES computation on a structured grid, which is first validated against experiments. The results highlight the improved results of the ZDES compared to RANS and show that the accuracy of the simulation is preserved as long as the ratio of the grid densities of the overlapping meshes remains low.
