The Nusselt numbers of horizontal convection [PDF]
Journal of Fluid Mechanics, 2020 We consider the problem of horizontal convection in which non-uniform buoyancy, $b_{\rm s}(x,y)$, is imposed on the top surface of a container and all other surfaces are insulating.

Nusselt number for steady periodically developed heat transfer in micro- and mini-channels with arrays of offset strip fins subject to a uniform heat flux [PDF]
International Journal of Heat and Mass Transfer 195, 123145 (2022), 2022 In this work, the Nusselt number is examined for periodically developed heat transfer in micro- and mini-channels with arrays of offset strip fins, subject to a constant heat flux. The Nusselt number is defined on the basis of a heat transfer coefficient which represents the spatially constant macro-scale temperature difference between the fluid and ...

"Ultimate state" of two-dimensional Rayleigh-Benard convection between free-slip fixed temperature boundaries [PDF]
, 2011 Rigorous upper limits on the vertical heat transport in two dimensional Rayleigh-Benard convection between stress-free isothermal boundaries are derived from the Boussinesq approximation of the Navier-Stokes equations. The Nusselt number Nu is bounded in

Convectively driven shear and decreased heat flux [PDF]
J. Fluid Mech. 759, 360-385 (2014), 2014 We report on direct numerical simulations of two-dimensional, horizontally periodic Rayleigh-B\'enard convection, focusing on its ability to drive large-scale horizontal flow that is vertically sheared.

Upper bounds on Nusselt number at finite Prandtl number [PDF]
Journal of Differential Equations, 2016 We study Rayleigh B nard convection based on the Boussinesq approximation. We are interested in upper bounds on the Nusselt number $\mathrm{Nu}$, the upwards heat transport, in terms of the Rayleigh number $\mathrm{Ra}$, that characterizes the relative strength of the driving mechanism and the Prandtl number $\mathrm{Pr}$, that characterizes the ...

Nusselt Number Correlation for Vertical Tubes with Inverted Triangular Fins under Natural Convection [PDF]
Energies, 2017 Vertical tubes with inverted triangular fins under natural convection are investigated experimentally. The thermal resistances of tubes with inverted triangular fins are measured for various fin numbers, fin heights, and heat inputs.

Radial boundary layer structure and Nusselt number in Rayleigh-Benard convection [PDF]
Journal of Fluid Mechanics, 2009 Results from direct numerical simulations for three dimensional Rayleigh-Benard convection in a cylindrical cell of aspect ratio 1/2 and Pr=0.7 are presented. They span five decades of Ra from $2\times 10^6$ to $2 \times10^{11}$.
