STUDI NUMERIK SEPARASI ALIRAN 3D AKIBAT PENAMBAHAN FFST PADA BIDANG TUMPU AIRFOIL ASIMETRI by Ika Nurjannah, Herman Sasongko, Heru Mirmanto

“…The parameters used in the free stream flow Re = 1.64 x 105 and Turbulence Intensity Tu = 0.3% to assess the comparison of the flow characteristics on the endwall of the British 9C7 / 22.5C50 asymmetric airfoil due to the addition of a FFST and without FFST with variations angle of attack (α) of 00, 80, 120, 140, 160 .The results show that the addition of FFST can increase the turbulent intensity in the area near the wall which turns into momentum, so that it has an impact on the ability of the flow to overcome the adverse pressure in the trailing edge area and further backward (delayed) separation which results in smaller wake. …”
