Abstract

Turbulent flow past low aspect ratio (AR) thin wing with two different planform shapes viz., rectangular and inverse Zimmerman has been carried out at a Reynolds number (Re)=2.4´105 to analyze their aerodynamic characteristics using the Unsteady Reynolds Averaged Navier Stokes (URANS) equations coupled to k-e turbulence model. In the present work the aerodynamic characteristics of thin wings with different planforms are studied and the three dimensional effects which are prominent in low AR are also discussed by comparing with 2D simulations carried out for the root section of the wing.
