Looking for experimental data for Ahmed body

Anna Tian · February 4, 2014, 04:11

Hi,

Could someone provide me the experimental data Cl and Cd for Ahmed body or the link to find them?

The standard one would be

S.R. Ahmed, G. Ramm, Some Salient Features of the Time-Averaged Ground Vehicle Wake, SAE-Paper 840300, 1984

although I am not sure if they have given Cl data, Cd however they have

I have done some comparisons with Ahmed body (experiments) and CFD, if you are interested in that I can send you a copy

Yes. Thank you very much.

Would you like to send me a link so that I can download them or you would like to send me them by email?

I once checked this website. It doesn't contain the measurement data for Cl and Cd.

actually there are, but you have to log in somewhere (had the same problem a while ago)

I'm confused. I registered in. But the webpage I see is still the same to the webpage before. The only difference is I can open the .dat files. But I still have no clue where is Cl and Cd data. I only find a Cd graph in their paper. Could anyone help?
