The wall interference effect of the ONERA-M6 wind tunnel testing is analyzed using CFD analysis. The computational domain includes the wind tunnel walls, and the effect of the porous walls, which are set at the top and bottom of the test section, are computed by the porous wall model. The computational result gets almost the same shock wave shape as the experiment, which could not be captured in the past works. The interference by the porous walls decrease the Mach number and the incidence, and the swept angle of front shock wave and the location of rear shock wave are altered. The lift and drag coefficients are also affected by the interference of the porous wall. The lift coefficient becomes small due to decrease of the incidence. The smaller Mach number decreases drag coefficient, meanwhile decrease of the attack angle causes additional drag by similar mechanism to induced drag.
