Hi all,
Considering that the velocity profile near the boundary of an airfoil (e. g. at 20%c distance from the LE) has the following form: How can I measure the boundary layer thickness? The free stream velocity is 1m/s, but the velocity doesn't get close to this value until relatively far from the airfoil. |

What is your Reynolds number? Unless you are modeling a very small airfoil, a velocity of 1 m/s is going to result in a very thick viscous region around the airfoil. The term boundary layer may not even apply.

The fluid is air, and the chord of the airfoil is 1 m. Yes, the Reynolds number is quite high. I will think about it. Thank you!
