A version of the global Galerkin method applied to a wide range of hydrodynamic stability problems is described. The numerical algorithm is based on a non-orthogonal set of globally defined basis functions, which satisfy all linear boundary conditions and the continuity equation. This leads to a significant reduction of the number of scalar degrees of freedom of the numerical model. The relatively low number of degrees of freedom makes it possible to solve the eigenvalue problem associated with… CONTINUE READING
