Abstract A new algorithm for the solution of laminar viscous‐inviscid interactions allowing for the formation of pronounced separation zones is presented. It is then applied to two different types of flows: near critical two layer fluid flow and subsonic flow past an expansion ramp. In the first case emphasis is placed on the formation of so‐called non‐classical hydraulic jump having the distinguishing property that waves pass through rather than merge with the jump. The second problem exhibits the interesting feature that no solution exists if the ramp angle exceeds a critical value while two solutions exists if the ramp angle is subcritical. The new numerical scheme is used to study the change in the flow behaviour as the critical ramp angle is approached. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
