Turbulent-Laminar Patterns in Plane Couette Flow,be tilted at any prescribed angle to the streamwise direction. We report on different patterned states observed as a function of Reynolds number, imposed tilt, and length of the long direction. We compare our findings to observations in large aspect-ratio experiments.

Instability, Transition and Turbulence in Plane Couette Flow with System Rotation,pes of secondary instabilities, especially interesting is a repeating pattern of wavy structures followed by breakdown, thereafter roll cells reappear in a cyclic pattern. For higher Reynolds number roll cells appear also in a turbulent environment. It is also shown how stabilizing rotation may quench the turbulence completely.

The limited data available to date suggest that the upper branch states provide a good first approximation to the statistics of turbulent flows. The upper branches may thus be understoo

In our case computational domains are of minimal size in only two directions. The third direction is taken to be large. Furthermore, the long direction can
