Transformation thermal convection: Cloaking, concentrating, and camouflage [PDF]
Phys. Rev. E 97, 022129 (2018), 2017 Heat can generally transfer via thermal conduction, thermal radiation, and thermal convection. All the existing theories of transformation thermotics and optics can treat thermal conduction and thermal radiation, respectively. Unfortunately, thermal convection has never been touched in transformation theories due to the lack of a suitable theory, thus ...

Side-heated Rayleigh-Bénard Convection [PDF]
arXiv, 2021 Unlike solids, the heat transfer in fluids can be greatly enhanced due to the presence of convection. Under gravity, an unevenly distributed temperature field results in differences in buoyancy, driving fluid motion that is seen in Rayleigh-B\'enard Convection (RBC).

Latitudinal regionalization of rotating spherical shell convection [PDF]
, 2022 Convection occurs ubiquitously on and in rotating geophysical and astrophysical bodies. Prior spherical shell studies have shown that the convection dynamics in polar regions can differ significantly from the lower latitude, equatorial dynamics. Yet most spherical shell convective scaling laws use globally-averaged quantities that erase latitudinal ...

Convective Heat Transfer in Porous Materials [PDF]
arXiv, 2023 Thermal convection stands out as an exceptionally efficient thermal transport mechanism, distinctly separate from conduction and radiation. Yet, the inherently elusive nature of fluid motion poses challenges in accurately controlling convective heat flow.

Rayleigh-Bénard thermal convection perturbed by a horizontal heat flux [PDF]
arXiv, 2021 In Rayleigh-B\'enard convection, it has been found that the amount of heat passing through the fluid has a power law dependence on the imposed temperature difference. Modifying this dependence, either enhancing or reducing the heat transfer capability of fluids, is important in many scientific and practical applications. Here, we present a simple means

Lattice Boltzmann simulations of three-dimensional thermal convective flows at high Rayleigh number [PDF]
International Journal of Heat and Mass Transfer 2019, 140, 359-370, 2019 We present numerical simulations of three-dimensional thermal convective flows in a cubic cell at high Rayleigh number using thermal lattice Boltzmann (LB) method. The thermal LB model is based on double distribution function approach, which consists of a D3Q19 model for the Navier-Stokes equations to simulate fluid flows and a D3Q7 model for the ...
