Two-Velocities Hybrid RANS-LES of a Trailing Edge Flow

  • Conference paper

Part of the book series: IUTAM Bookseries ((IUTAMBOOK,volume 14))

Abstract

The flow around a trailing edge is computed with a new hybrid method designed to split the influences of the averaged and instantaneous velocity fields. The model is first tested on channel flows at different Reynolds numbers and coarse meshes giving good predictions of mean velocities and stresses. On the trailing edge flow the predictions of the hybrid model are compared with those using DES-SST on the same coarse mesh. The results of the hybrid model are close to the reference fine LES in terms of mean velocity and turbulent content.
