4 difference method for treating the complete two-dimensional Navier-Stokes equations in time-dependent form is applied to the prediction of incipient turbulence. A steady laminar flow profile is disturbed and the propagation of disturbances in time and space is calculated. Changes occur in amplitud

A direct numerical scheme is developed to study the temporal ampliยฎcation of a 2D disturbance in plane Poiseuille ยฏow. The transient non-linear NavierยฑStokes equations are applied in a region of wavelength moving with the wave propagation speed. The complex amplitude involved in the perturbation fun
Several results using numerical experimentation on homogeneous three-dimensional turbulent MHD flows are reviewed. The role (or absence thereof) of chaos and that of kinetic helicity for the kinematic dynamo problem is described. A second topic concerns the formation of large scale coherent structur
## Abstract This paper examines the performance of optimal linear quadratic state and output feedback controllers in stabilizing twoโdimensional perturbations in a plane Poiseuille flow. The synthesis of the controllers is based on a linearized model of the flow using a new set of interpolating pol
