Abstract

We present simulations of turbulent detached flows using the commercial lattice-Boltzmann solver, XFlow. Using traditional Computation Fluid Dynamics (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 using octree structures. 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 industrial cases: first, the Goldschmied Body10 at Re= 8.9 ·104 . Second, the HLWP-2 (2nd High-Lift Prediction Workshop)19 geometry, which represents a full aircraft at Re= 1.35 · 106 and Re= 15.1 · 106 . Third, a dynamic stall for a NACA001215 at Re= 0.98 · 106 for a reduced frequency, k = 0.1. Finally, a parametric study to improve wing stall using tubercles located at the leading edge at Re/L = 4.66 · 106 with a reference length, L.
