Abstract: In this talk, the experimental realization of Kolmogorov flow is discussed, in the context of
trying to achieve quantitative agreement with the doubly-periodic simulation, presented in our last meeting.
The sequence of bifurcations in the "original" geometry are briefly presented. The effects of changing
the boundary conditions are shown; we choose a new geometry which improves the agreement with the
simulation. Preliminary results of recurrence searches across experimental data and between experiment
and numerics are presented.
