Assessment of the steady swirling flow stability using amplitude-frequency characteristic
Original language description
Paper presents description of the methodology for assessing swirling flow stability. In contrast to current approach, CFD is only used supplying of the steady velocity field. Rest of the analysis is done by solution of the eigen value problem, which is formed by linearized Euler equations. Numerical procedure based on spectral element method in combination with forced oscillations solution enables to determine a set of eigen frequencies of the swirling liquid. Presented method is a fast tool to assess stability of the draft tube flow for different inlet velocity boundary conditions or different draft tube shapes.
