The fluidelastic force induced by a confined flow in a bidimensional flow channel, has been determined by using a method which takes into account the dissipative effects by a linearizing of the pressure losses considered as boundary conditions. This force has been used to study the stability of a two-degree-of-freedom structure for several boundary conditions. The motion equation of the system can be solved with an iterative method, and a parametric study has been carried out. The results obtained show the appearance of a flutter instability which has been largely influenced by the position and the value of the pressure losses.
