Direct numerical simulations of chevrons, blinking states, and repeated transients in binary fluid mixtures
with a negative separation ratio heated from below are described. The calculations are performed
in two-dimensional containers for experimental parameter values and boundary conditions. Quantitative
agreement with the experiments of Kolodner [Phys. Rev. E 47, 1038 (1993)] is obtained, and the origin
of the blinking and repeated transient states is elucidated.
