摘要：

The incompressible Navier-Stokes equations are numerically integrated on a Cray-2 machine with the periodic Taylor-Green initial data. Using a spectral method taking advantage of the symmetries of the flow, a resolution of 864(3) and corresponding high Reynolds numbers (R(lambda) = 140) are obtained Visualisations of the resulting turbulent flow show that the turbulent activity is strongly correlated with low-pressure zones. We demonstrate that this behavior of the pressure field is linked to the fact that the square vorticity is spatially more concentrated than the energy dissipation.
