Numerical studies of unsteady boundary layer flows past an impulsively started circular cylinder by GDQ and GIQ approaches Original Research Article

The global methods of generalized differential quadrature (GDQ) and generalized integral quadrature (GIQ) are applied to simulate two-dimensional, unsteady, laminar boundary layer flows past an impulsively started circular cylinder. The present results compare well with other researchersʹ results, which confirm that there is a finite time singularity in the solution of unsteady boundary layer equations.
