Abstract:The flow and aerodynamic noise of a generic side mirror in high-speed is evaluated using numerical simulation and experiment. The Reynolds number is R e = 5.2 X 105 basing on the mirror diameter. Transient flow field is analyzed by Large Eddy Simulation (LES), two different sub-grid scale (SGS) models named Smagorinsky-Lilly (SL) and Wall Adapting Local Eddy-viscosity (WALE) are used to express the turbulent viscosity. Detailed velocity vectors and pressure fluctuation contours are compared by cut planes in th… Show more
