A two-dimensional incompressible isothermal laminar separation of a Newtonian fluid in steady flow was investigated. The geometry chosen for this study was a constant-width channel with a sharp 90-deg turn. It was found that an adaptation of a numerical solution for the Navier-Stokes equations first proposed by Allen gave convergence for all Reynolds numbers in the laminar range. The analytical results were compared with measured velocity profiles from a very low-speed wind tunnel.
