Airfoils and lift compared to air density and TE

Jens

Hi,

I am studing a flare system with compbustion and high speed flow using CFD simulation. I would like to compared the flow in the vicinity of the flare plume to data regarding the stability of an airfoil.

That means I am looking for what range is a generel airfoil of a airplane (small airplane) stabel.

Like a minimum limite of the air density ?

And what levels should the turbulence kinetic energy be below ?

Does anyone knows were to find such information ???

Thanks on advance.

Kind regards

Jens
