Experimental and numerical investigation of turbulent natural convection in a large air-filled cavity (2004, background): “Our first point at the wall is located at xþ 1, and there is nearly 6 points in the thermal boundary layer, as recommended for example by Verzicco and Camussi (2003) for direct numerical simulation of turbulent thermal convection.”
Confined turbulent convection (2002, background): “Verzicco & Camussi (2003) observe, for Γ = 1/2, that the mean wind changes from a weak re-circulation over the entire height of the apparatus, coupled with a stronger but more localized toroidal roll at the top and bottom boundaries at low Ra, to a two-cell structure of equal size, stacked one…”
The Sun’s Supergranulation (2010, background): “The highest-supercritical simulations to date (Ra/Racrit ∼ 1011, see Verzicco and Camussi 2003; Amati et al. 2005; Lohse and Xia 2010) require numerical spectral resolutions of the order of ∼ 5123 to ∼ 10003 grid points to simulate turbulent convection in numerical domains of comparable vertical…”
Radial boundary layer structure and Nusselt number in Rayleigh–Bénard convection (2009, methodology): “This is due to the flow organization at higher Ra; see figure 8 of Verzicco & Camussi (2003), where it is shown that there is a double convection roll for Ra = 2 × 109.”
Heat transfer and large scale dynamics in turbulent Rayleigh-Bénard convection (2008, methodology): “We mention briefly that DNS revealed two counter-rotating near-circular rolls, stacked vertically one above the other (Verzicco and Camussi (2003)) as the dominating feature of the LSC in cylindrical samples with Γ ∼ 0.5.”
Heat transport by turbulent Rayleigh–Bénard convection in cylindrical cells with aspect ratio one and less (2004, background): “For Γ 0.5, on the other hand, Verzicco & Camussi (2003) suggest that the system contains two or more rolls placed vertically one above the other.”
Aspect ratio dependence of heat transfer and large-scale flow in turbulent convection (2010, methodology): “This can be attributed to the complex flow configuration in the slender cell, in which there are either two counter-rotating rolls on top of each other, or one slender roll (Verzicco & Camussi 2003, Xi & Xia 2008a).”
