Descrição: Subsequent numerical investigations modeling this geometry have tended to focus on two-dimensional geometry representing the semispan point of the full wing (z/b= 0), and several studies have made comparisons between turbulence models and meshes in an attempt to determine the best approach for such flows. The two-dimensional computational results reported in literature indicate not only a persistent and significant overestimation of the suction peak of the lower surface, and thus an over prediction of lift coefficient, but also an unusually large spread of pressure distributions produced by different turbulence models. The present investigation determines the applicability or otherwise of two-dimensional simulations of the T-026 wing and similar configurations, and in doing so characterizes any wall effects that may also be influencing experimental results obtained.
