A Boundary Layer Model for Unbounded Flow Along a Wall
Abstract
The current boundary layer model used in describing flow along a wall is found to be incomplete in that it only describes the flow found in a wind tunnel. The important attribute of the wind tunnel case is that the velocity above the wall asymptotes to a constant value that is different than the free stream inlet velocity. In contrast, for flows along an airfoil, the velocity above the airfoil surface must eventually return to the free stream inlet flow velocity value. Hence, a new boundary layer model is required for this case. Herein, we define a new region above the viscous layer as the inertial boundary layer region. New thickness and shape parameters are defined and similarity solutions are proposed
