Abstract
The problem of small free oscillations of a membrane that is orthogonal to an inflowing stream is considered. A quasi-cavitation numerical hydrodynamic scheme is used that combines the assumptions on the potential character of the flow before the membrane and the assumption of a constant bottom pressure. The problem is reduced to a homogeneous system of integral-differential and singular integral equations with respect to variables that give the form of the membrane and density of associated whirls. For a small velocity pressure an analytic solution to the problem in the first order of the perturbation theory is constructed. Analytic and numerical solutions to the problem are compared, which are obtained by using the methods of finite differences and “discrete” whirls.
