Reynold's number and boundary layer separation
 
Reynold's number describes the ratio of inertial forces to viscious forces. This means greater viscosity means less Reynold's number, which means more laminar flow.
But then in a boudary layer of an airfoil, the airflow is turbulent(high Reynold's number) yet very viscious so how does this work? What am I missing? Thanks in advance.:confused:
