Vorticity evolution in perturbed Poiseuille flow

Vorticity evolution in perturbed Poiseuille flow

We consider numerical simulation of temporal hydrodynamic instability with finite amplitude perturbations in plane incompressible Poiseuille flow. Two dimensional Navier Stokes equations have been used and reduced to vorticity-stream function form. Trigonometric polynomials have been used i...
