ahmed body aerodynamics literature review
 

hi all,

i was trying to simulate the ahmed body case with openfoam recently, and no matter how i changed the mesh (inflation/boundary layer thickness, boundary layer cell count, mesh refinement with boxes ...) i could not reach the drag values reported by Ahmed et al. with kOmegaSST and kOmega2006 turbulence models (did not test any other model).

so i did a literature review and searched for publications in which openfoam was used for the ahmed body case. my findings are attached as a screenshot.

as one can see, no publication is consistent with the drag value reported in Ahmed et al.

so i wonder, if it is worth still trying to tweak the numerics to reach the reported values by Ahmed et al. or if the state-of-the-art is not sufficient.

Hi,

could you please give the full literature references you found please? Thanks!
