This paper presents the results of unsteady Lattice Boltzmann simulations of the JAXA high-lift configuration Standard Model (JSM) in the JAXA Low speed Wind Tunnel. The study is a part of a continuing collaboration between JAXA and Dassault Systèmes and focuses primarily on unde ...
Unsteady transonic Lattice Boltzmann simulations of the NASA Common Research Model in the European Transonic Windtunnel are presented. Modelling of the slotted wall transonic test section is described and different simulation approaches are discussed. Quantitative comparisons ar ...
Transonic buffet simulations are carried out for the OAT15A airfoil and the NASA Common Research Model. Simulations are performed with a Lattice-Boltzmann based solver, which has been extended to transonic flow capabilities. The results are compared to data from the literature, i ...
A Lattice-Boltzmann flow solver is used to simulate the unsteady flow around swept and unswept wings in the presence of ice shapes on the leading edge. The stall mechanism is studied for roughness ice, ice horns, and scallop ice. These types of flows are particularly challenging, ...
Unsteady simulations using PowerFLOW, a Lattice-Boltzmann-method-based solver, of a rectangular deep (L/D= 4.5), open-flow cavity at subsonic and supersonic speeds (M= 0.6 to 1.5) are presented. Acoustic sound pressure levels and cavity modes are compared to experiments and analy ...
