Stability Analysis of the Lower Branch Solutions of the Falkner-Skan Equations.

Abstract

The stability of the Lower-Branch solutions of the Falkner-Skan boundary layers has been analyzed. A perturbation analysis of these boundary layers was performed resulting in the Rayleigh stability equation. Eigenvalue solutions were obtained for the Rayleigh equation for different adverse pressure gradient values. Propagation velocity and amplification factors were computed over the entire range of unstable wave numbers. All retarded flows were found to unstable for a small range of frequencies, with the amplification factor increasing as the extent of reversed flow increased. (Author)
