Hi everyone,



I am a little confused with the relation of lift coefficient with the Reynolds number. As, I did a comparison of lift/drag coefficients from CFD plotted against angle of attack (Re=0.3 million) with higher Reynolds experiment (Re=3 million).

The drag coefficient at higher Reynolds is lower than one in the CFD simulations which makes me assume that at higher Reynolds number flow becomes more energized such that it penetrates through the zone of high adverse pressure gradient consequently the drag is reduced.


However, the lift coefficient at higher Reynolds (experiment) is HIGHER compared to the CFD results. Could you please describe this behavior in light of following attached images?


Thanks for your time.
