The dynamics of a fully three-dimensional lid-driven cubical cavity (3D-LDC) flow at several post-critical conditions, i.e., beyond the first bifurcation, are elucidated using both linear and nonlinear analyses. When Reynolds number is increased critical value, symmetry breaks down intermittently with subsequent gradual growth in spanwise inhomogeneity. This results crossflow as well pronounced...
