AbstractThe now of two-dimensional airfoil inside wind tunnel is analyzed by CFD method with a new porous wall model. Results of CFD analysis using porous wall model agree with experimental values, however in the case of no porous wall model, the results are different. These computations show the CFD analysis with the new porous wall model can precisely simulate the flow in wind tunnel. The wind tunnel wall affects the flow by deflecting and blockage. Flow through the porous wall changes incident angle of the airfoil, as a result, the lift ccefficient becomes small. 0n the other hand, in the solid wall cases, the blockage effect becomes quite large and flow acceleration increases near the airfoil. Therefore lift coeffient and drag coefficient become large.
