Numerical Prediction of the Aerodynamics and Acoustics of a Tip Leakage Flow Using Large-Eddy Simulation

A Large-Eddy Simulation of the tip leakage flow a single airfoil is carried out. The configuration consists non-rotating, isolated between two horizontal plates with gap 10 mm and lower plate. Mach number incoming 0.2, Reynolds based on chord 9.3 × 105. objective present study to investigate best way compute both aerodynamics acoustics flow. In particular, importance inflow conditions prediction vortex loading underlined. On other hand, complex structure its convection along was recovered due use mesh adaptation dissipation kinetic energy. Finally, ability wall law model in region proven terms pressure fluctuations far-field.
