Abstract

A method for decomposition of an experimental signal that contains several normal modes with a prescribed frequency, is proposed The method is based on an expansion of solutions for small-amplitude spatially growing disturbances in a biorthogonal eigenfunction system. It is shown that data of one velocity component at a given cross-stream section of the flow are in some cases, sufficient for the decomposition. The method is applied successfully to analyze small-amplitude periodic disturbances in a transitional wall-jet flow.
