Abstract
A new interacting boundary-layer method is developed for calculating two-dimensional incompressible laminar separation bubbles. The method relies on a completely consistent mixed boundary value treatment of the outer inviscid flow. For attached flows, the new method is found to converge as fast as the classical Cauchy-Hilbert method and to yield the same solutions. For separated flows, the new method is found to converge two to three times faster than a comparable Cauchy-Hilbert method. The physical asymptotic theories that underlie this new numerical method will be discussed, in so far as they motivate the method.
