Two series of visualization experiments were performed in the boundary layer of Rayleigh—Bénard convection with the goal to get more information on the behavior and characteristics of streaks elongated in the streamwise direction observed in the boundary layers. These streamwise streaks are a new type of coherent structures in the Rayleigh—Bénard convection.
