Chapter 5 -- Effect of Plumes on Measuring the Large Scale Circulation in Turbulent Rayleigh-Bénard Convection

Movie 5.1: Movies of a) the temperature field at the heights 0.25L, 0.50L, and 0.75L and b) the temperature and velocity field in a vertical cut for the simulation at Ra=1x10⁸, Pr=6.4, and Γ=1.0 on the 385x193x385 grid. The dimensionless time is indicated in the top of the movies. This movie is rendered with a lower resolution for the website.

Movie 5.2: The azimuthal vertical velocity profile averaged over 4 τ_f for Pr=6.4 in a Γ=1 sample at Ra=5x10⁸ over time based on the data of only 8 probes (a) and all 64 (b) probes. See also figure 5.8 of the thesis.

Movie 5.3: Movies of a) the temperature field at the heights 0.25L, 0.50L, and 0.75L and b) the temperature and velocity field in a vertical cut for the simulation at Ra=1x10⁸, Pr=0.7, and Γ=0.5 on the 257x97x385 grid. The dimensionless time is indicated in the top of the movies. This movie is rendered with a lower resolution for the website.

Movie 5.4: Movies of a) the temperature field at the heights 0.25L, 0.50L, and 0.75L and b) the temperature and velocity field in a vertical cut for the simulation at Ra=1x10⁸, Pr=6.4, and Γ=0.5 on the 193x65x257 grid. The dimensionless time is indicated in the top of the movies. This movie is rendered with a lower resolution for the website.

Movie 5.5: Three-dimensional view on the snapshot of the regions with the strongest, i.e. w ≥ 0.35 w_max, up (red) and down-flow (blue) for Ra=1x10⁸ and Γ 1/2. a) Pr = 0.7, SRS, b) Pr = 0.7, very strong corner flows, c) Pr = 6.4, DRS, d) Pr = 6.4, strong plume/torsional motion.
