The instability of flow from two ducts that join into a common duct and the influence of the various parameters upon the phenomenon were investigated. A two-dimensional potential analysis was carried out under the assumption that the two ducts discharge into a region of constant pressure. A unique solution exists if a Joukowski hypothesis is imposed; also, the flow is stable with respect to small changes in the physical parameters. This was confirmed by experiments with a two-dimensional water table. The problem was reconsidered with the assumption of mixing between the jet from the two ducts and the surrounding fluid in the common duct to explain the oscillations and asymmetries of flow for actual symmetric duct configurations.
