Web• The boundary layer equations can be extended to the case of non-constant mean flow ∞= ∞( , ): + =0 + + = ∞ + ∞ ∞ + 1 𝜏 • Here 𝜏is the shear stress which for laminar flows has the familiar form: Note: The above form of the boundary layer equation also holds for turbulent boundary layers, but with a different WebWith a general pressure gradient the boundary layer equations can be solved by a va-riety of modern numerical means. An alternative which can still be employed to simplify calculations is the momentum integral method of Karman. We explain this method for a transient boundary layer along the x-axis forced by an unsteady pressure gradient outside.
