抄録

In this paper investigation of two-dimensional wind-tunnel-wall interference is presented. The analysis is carried out using a traditional theoretical tunnel-wall corrections, a potential flow calculation by the vortex distribution method, and 2D Navier-Stokes simulations of the airfoil in the wind tunnel. The traditional theoretical tunnel-wall corrections are compared with the potential flow calculation. The agreement of the lift coefficients is satisfactory for the height-chord ratio larger than 2, and the moment coefficients are agree for the height-chord ratio larger than 4. The results of 2D Navier-Stokes simulations are compared with the small amount of low-speed experimental data available and the agreement is seen to be satisfactory, even for relatively small values of the height-chord ratio.
