Abstract

CFD analyses using Detached Eddy Simulation (DES) and Reynolds-Averaged Navier-Stokes (RANS) techniques are conducted on a two-element NLR 7301 airfoil configuration at take-off flow conditions to predict its near stall aerodynamic performance. Meshing tool ICEM is used to generate a block-structured grid and simulations are performed for angle of attack (AoA) up to 16 degrees. Some key physical flow phenomena such as flow unsteadiness and separation are addressed. Comparisons with available experimental data are carried out to assess the capability of DES and RANS methods to predict stall performance in terms of their accuracy and efficiency.
