k-w SST with or without Low Re Correction?
 
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!

Thanks,

Orion

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?
