Abstract:We measured the three-dimensional velocity field of a large-scale reorientation in turbulent Rayleigh-Bénard convection with a high Rayleigh number Ra = $2.5\cdot 10^9$ by long-term particle tracking velocimetry measurements over 30 hours in a water-filled cubic cell with a side length of $L=300$ mm. Reorientations are characterized by the large-scale circulation in the flow changing its orientation from one cell diagonal to the other, and they are rare events; one can expect about one reorientation per day in… Show more
