Abstract:
We report experiments on spatially forced inclined layer convection, where the combined effect of the
intrinsic symmetry breaking due to a gravity-induced shear flow and spatially periodic 1D forcing is
studied. We observed pattern selection processes resulting in stabilization of spatiotemporal chaos and the
emergence of novel two-dimensional states. Phase diagrams depicting the different observed states for
typical forcing scenarios are presented. Convection in the weakly nonlinear regime is compared with
theory, and a good agreement is found.
