Longitudinal vortices are a common flow phenomenon in the flow around aircraft. They emerge wherever sharp edges are encountered and affect the stability of the boundary layers with which they inte...

The interaction of a generic longitudinal wake vortex with an HGR-01 single-element airfoil is simulated with hybrid RANS/LES and compared with reference RANS results. The influence of different grid types in the vortex transport region, either struc

This contribution presents the application of the JHh-v2 and JHh-v3 Reynolds-Stress-Model on different test cases with free shear layers. Based on a two-dimensional mixing layer, the need for improvement of the JHh-v2 turbulence model for free shear

The present paper analyzes the vortical flow downstream of a delta wing. The delta wing is designed to generate a vortex that resembles the vortex of a nacelle strake. The experimental results of s...

Results of numerical simulations on a high-lift configuration with an Ultra High Bypass Ratio (UHBR) engine are shown. In the area of the integrated engine, a complex vortex-system develops. Different longitudinal vortices proceed downstream on the s

The results of numerical simulations on a generic high-lift configuration are shown. The high-lift airfoil features a finite slat, where the slat-end creates strong longitudinal vortices interacting with the flow along the suction side. For the simul
