Presents a computationally efficient, cell dynamical system which mimics the two-component Ginzburg-Landau equation. This model is used to numerically study the time-dependent behaviour of the vorticity number for a two-dimensional lattice. The author finds that the vorticity number initially decays exponentially in time and subsequently shows a power-law decay in time ( approximately 1/t, where t is time).
