Laminar Boundary Layer Thickness in Flow over Airfoils and Wings Formulas

Laminar Boundary Layer Thickness is the distance normal to the wall to a point where the flow velocity has essentially reached the ’asymptotic’ velocity, or 99 percent of freestream velocity. And is denoted by δ_L. Laminar Boundary Layer Thickness is usually measured using the Meter for Length. Note that the value of Laminar Boundary Layer Thickness is always positive.
