Kurzfassung
Overlapping grid technique (Chimera) is combined with an automatically generated cartesian background grid to descretize the flow domain around a helicopter fuselage model. Three dimensional Navier-Stokes computations are performed with the DLR's CFD code FLOWer to predict air flow past an Eurocopter BO-105 fuselage under low Mach number forward flight conditions. The influence of several turbulence models of the two-equation k-w type is analyzed via direct comparison with the measured pressure distributions and aerodynamic coefficients. Among the models considered, the SST model showed the best agreement with the experimental data.
