Integral boundary layer formulation
NettetThe boundary layer equations can be written in the form (see e.g. Schlichting [21 ]) (1a) (1b) (1c) where u = ( u, v) is the velocity, u is tangential to the boundary and v is normal to the boundary, x is the spatial coordinate tangential to the boundary and y is the coordinate normal to the boundary, ξ is the vorticity and v is the viscosity.
