A numerical and theoretical study of the first Hopf bifurcation in a cylinder wake

J Dušek, P Le Gal, P Fraunié - Journal of Fluid Mechanics, 1994 - cambridge.org
The first Hopf bifurcation of the infinite cylinder wake is analysed theoretically and by direct
simulation. It is shown that a decomposition into a series of harmonics is a convenient …

Breaking of axisymmetry and onset of unsteadiness in the wake of a sphere

B Ghidersa, JAN Dušek - Journal of Fluid Mechanics, 2000 - cambridge.org
