โœฆ Synopsis

By applying the singularity subtraction technique to the unsteady driven cavity problem, the stability of the impulsively started flow is investigated, without smoothing the corner singularity. A second-order spectral projection method allows localization of the critical Reynolds number for the first Hopf bifurcation in the interval [8017.6, 8018.8).

We present results of a stability analysis of the lid-driven cavity flow based on classical C 0 finite element discretizations of the Navier-Stokes system. Using arc length continuation and subspace iteration to compute the eigenvalues of the tangent operator, we study the dependence of the bifurcat
