We develop a model and numerical method to study the large-amplitude flutter of rectangular membranes (of zero bending rigidity) that shed trailing vortex-sheet wake in three-dimensional (3-D) inviscid fluid flow. apply small initial perturbations track their decay or growth steady-state motions. For 12 combinations boundary conditions at membrane edges we compute stability thresholds subsequen...

Most of river engineering problems are complicated and need to be analyzed by three dimensional models of flow and sediment transport. Considering the fact that computers and numerical methods with great ability of flow and sediment transport simulation are developing quickly, using numerical modeling by engineers is inevitable. Nevertheless, before application, numerical models need to be veri...
