Default NACA 0012 pressure !!!!!!
Posts: n/a
Dear all, I just made a program to simulate the pressure distribution around NACA 0012 based on artificial compressibility method. But my pressure distribution Cp(=-0.7) is higher than exp. data(=-1.2) around leading edge when Re=7.6*10^5,AOA=4 degree.I cannt find out why, anybody can help me this? Anyway, my result is good agreement with exp. data for AOA=0. Laminar and k-e model been tried,the mini grid distance on surface is about 0.001. Thanks help! Dexin
