Remarks on Kelvin's Solutions of Shear-flow Systems - a Generalized Modal Approach -

抄録

The structure of Kelvin's method, which is driving great advances in the study of shear-flow systems, has been carefully re-examined. It is shown that this method is a particular case of a generalized modal approach. The generality of Kelvin's solutions, which is an essential issue in the study of stability, is also proved. The possibility of extending Kelvin's method to the treatment of systems presenting spacial inhomogeneities other than the convective is discussed.
