摘要
The Information in frequency domain was deducted by a discrete Fourier transforms. The modal information of the fluid-structure interaction in internal flows was analyzed. The dispersive and dissipative term in a fully coupled manner can be treated. The method has been validated by comparison with an exact analytical solution, with the results obtained by discrete Fourier transform and an analysis using the method of characteristics as well as with measured data from a laboratory apparatus.
