Abstract

We measure the velocity field in a horizontal field near the hot plate in turbulent convection using stereo PIV for \({10^6<Ra_w<10^9}\) and \({5.2<Pr<4}\). We then extract the line plumes from this velocity field using a divergence criterion using the PIV technique on the obtained plume structures, which gives us the velocity field of the plume motion. The statistical analysis of this velocity field of the plume motion shows the coexistence of two different kinds of motion of the plumes, lateral merging and motion along the plumes.
