Hi Guys,

I am simulating an airfoil with reynolds numbers between 200,000 and 900,000 using the k-omega SST model and was wondering if I should be using the low Re correction option? When I turn it on, there seems to be separation bubbles that get closer to the leading edge as the Re increases, although when compared with Xfoil it predicts the bubbles a lot closer to the trailing edge. When the low Re correction is off, there don't appear to be any separation bubbles at all.

Any help would be much appreciated!

I would also like to know this.
Low-Reynolds correction in k-omega refers to the reference Reynolds number of the problem or the boundary layer grid resolution?

If it refers to the reference Reynolds, then what is considered as Low?
