Default 3D Turbulent Ahmed body flow
Posts: n/a
hi everyone. my question is about Ahmed Body. have you ever used this 3D problem for your validation cases. my problem is the material properties of air. my drag coefficient is %30-40 higher than the experimental value. I used ro as 1.14075 kg/m3 (@ h=426m T=20Celcius). the height is the geographical altitude of the Gottingen city that the original experiment conducted. but there is no info about material properties. does anyone interested in this topic?
