| We present turbulent flows simulated using the commercial Lattice Boltmann solver XFlow. Using traditional CFD software, industrial problems require time consuming meshing processes. Due to its particle-based methodology, the meshing complexity is reduced in XFlow, allowing to solve complex geometries easily. However, this ease for meshing rises the question of accuracy to compute detached flows. The performance of XFlow will be demonstrated for different industrial benchmarks and compared to experimental data. We select four turbulent cases: first, the backward-facing step at Re=5100, second, a circular cylinder at Re=3900, third the Goldschmied Body [3] at Re=8.9 e4. Finally, the HLWP-2 (Second High-Lift PredictionWorkshop) geometry, which represents a full aircraft at Re=1.35 e6 and Re=15.1 e6. The latter case is a high-lift confguration with unstowed flap and slat, including slat tracks, flap track fairings, and slat pressure tube bundles. | |
