High Reynolds number steady laminar flow separation on nonlifting streamlined bodies was investigated by adopting an iteration scheme using the velocity-vorticity formulation. The Helmholtz vorticity equation is solved with its velocity coefficients presumed known from the previous iteration. The formulation is evaluated in two dimensions by application to a flat plate and to a thin body. For these applications the second approximation equations are simplified through order of magnetitude analysis; analytic solutions for the second approximation result. A third approximation is evaluated in both of the two dimensional applications. The third approximation results show improvements over the second approximation results.
