Numerical experiments on strongly turbulent thermal convection in a slender cylindrical cell (2003, background): “Rayleigh numbers: symbols present results; ——, experimental data by Roche et al. (2001); – – – –, experimental fit Nu = 0.”
From laminar plumes to organized flows: the onset of large-scale circulation in turbulent thermal convection (2004, background): “…al. 1996; Cioni et al. 1997; Qiu & Xia 1998a, b; Verzicco & Camussi 1999; Ashkenazi & Steinberg 1999; Qiu, Yao & Tong 2000; Grossmann & Lohse 2000; Niemela et al. 2001; Sreenivasan, Bershadskii & Niemela 2002; Lam et al. 2002; Grossmann & Lohse 2002, 2003; Nimela & Sreenivasan 2003; Xia, Sun &…”
The Sun’s Supergranulation (2010, background): “These so-called thermal winds are also observed in laboratory experiments on convection (e.g., Krishnamurti and Howard 1981; Sano et al. 1989; Niemela et al. 2001; Xi et al. 2004, and references therein).”
Prandtl and Rayleigh number dependence of heat transport in high Rayleigh number thermal convection (2011, background): “The simulation at Ra = 2 × 1012 with Pr = 0.7 in an aspect ratio Γ = 0.5 sample is in good agreement with the experimental results of Niemela et al. (2000, 2001), Niemela & Sreenivasan (2006), Funfschilling et al. (2009), and Ahlers et al. (2009a,b), while there is a visible difference with the…”
Confined turbulent convection (2002, background): “This is so because the mean wind, as inferred from measurements, oscillates rapidly – thus averaging over long times to negligible values (Niemela et al. 2001a; Sreenivasan et al. 2002).”
Heat transfer and large scale dynamics in turbulent Rayleigh-Bénard convection (2008, background): “…(Castaing et al. (1989), Heslot et al. (1987), Sano et al. (1989)), followed by the Grenoble group (Chavanne et al. (1997, 1996, 2001), Roche et al. (2001b, 2002, 2004)) and the Oregon/Trieste group (Niemela et al. (2000a, 2001), Niemela and Sreenivasan (2003a, 2006a,b), Niemela et al. (2000b,c)).”
The unifying theory of scaling in thermal convection: the updated prefactors (2013, background): “…for Ra & 1012, while all other experiments that have reached these Ra numbers are low temperature experiments with Helium close to the critical point (Chavanne et al. (1997, 2001); Niemela et al. (2000, 2001); Niemela & Sreenivasan (2006); Roche et al. (2010); Urban et al. (2011, 2012)).”
Radial boundary layer structure and Nusselt number in Rayleigh–Bénard convection (2009, background): “…for correspondence: r.j.a.m.stevens@tnw.utwente.nl Experimental results are controversial (Heslot, Castaing & Libchaber 1987; Chavanne et al. 1997; Niemela et al. 2000, 2001; Roche et al. 2002; Niemela & Sreenivasan 2003; Funfschilling et al. 2005; Nikolaenko et al. 2005; Funfschilling,…”
Rotations and cessations of the large-scale circulation in turbulent Rayleigh–Bénard convection (2006, methodology): “The turnover time in our experiments is 49 s at R = 1.1 × 1010, whereas Niemela et al. (2001) report a turnover time of about 30 s for R = 1.5 × 1010, so if the characteristic time scales for reversals are proportional to the turnover time, then we should expect them to be a little shorter for…”
