A GEOMETRICAL CONFIGURATION AND ITS EFFECT ON THE PERFORMANCE OF AN ELECTROCHEMICAL CELL UNDER FREE CONVECTION [PDF]
Journal of Engineering Science and Technology, 2018 The effect of positioning or location of the cathode electrode with respect to the surface margin of the electrodeposition electrolyte solution under free convection was numerically studied. The importance of such study arises from the fact that there is

Harnessing Outer Space for Improved Electrocaloric Cooling
Advanced Functional Materials, EarlyView.A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

The core helium flash revisited III. From Pop I to Pop III stars
, 2010 Degenerate ignition of helium in low-mass stars at the end of the red giant branch phase leads to dynamic convection in their helium cores. One-dimensional (1D) stellar modeling of this intrinsically multi-dimensional dynamic event is likely to be ...

Advanced Functional Materials, EarlyView.This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.

From zonal flow to convection rolls in Rayleigh-Bénard convection with free-slip plates [PDF]
arXiv, 2020 Rayleigh-B\'enard (RB) convection with free-slip plates and horizontally periodic boundary conditions is investigated using direct numerical simulations. Two configurations are considered, one is two-dimension (2D) RB convection and the other one three-dimension (3D) RB convection with a rotating axis parallel to the plate.
