摘要：

Secondary instability of flow past a circular cylinder is examined using highly accurate numerical methods. The critical Reynolds number for this instability is found to be Re-c = 188.5. The secondary instability leads to three-dimensionality with a spanwise wavelength at onset of 4 cylinder diameters. Three-dimensional simulations show that this bifurcation is weakly subcritical.
