Solution to industry benchmark problems with the lattice-Boltzmann code XFlow

This contribution presents some of the capabilities of the Computational Fluid Dynamics (CFD) code XFlow, which uses a proprietary particle-based kinetic solver based on the Lattice-Boltzmann Method. Using traditional CFD software, industrial problems require time consuming meshing process which often leads to errors or even divergence of the simulation. Due to its particle-based and fully Lagrangian approach, the complexity of the geometry surfaces is not a limiting factor in XFlow even in the presence of moving parts, allowing to solve real industrial problems. The performance of XFlow will be demonstrated for dierent industry benchmarks. The rst example is the Ahmed body which is a classical benchmark in the automotive industry. The second benchmark presented will be the NASA trapezoidal wing. XFlow results will be described and show good agreement with experimental data.
