Abstract

The stability of the near wake of a low aspect ratio cantilevered cylinder, with and without the influence of synthetic jet forcing, was estimated using piecewise two-dimensional inviscid stability analysis. Using a cusp method, the size of the 3-D vortex formation length was estimated. When the synthetic jet was activated it decreased the vortex formation length, altering the spectral content of the near wake, in agreement with experimental measurements. Furthermore, the turbulence intensity within the near wake could be estimated from the eigenfunctions corresponding to the most amplified spatial instability modes.
