The Dominance of Neutrino-Driven Convection in Core-Collapse Supernovae [PDF]
, 2012 Multi-dimensional instabilities have become an important ingredient in core-collapse supernova (CCSN) theory. Therefore, it is necessary to understand the driving mechanism of the dominant instability. We compare our parameterized three-dimensional CCSN simulations with other buoyancy-driven simulations and propose scaling relations for neutrino-driven

Viscoelastic Natural Convection [PDF]
, 2012 Heat convection occurs in natural and industrial processes due to the presence of temperature gradients which may appear in any direction with respect to the vertical, which is determined by the direction of gravity. In this case, natural convection is the fluid motion that occurs due to the buoyancy of liquid particles when they have a density ...

Vertical natural convection: application of the unifying theory of thermal convection [PDF]
J. Fluid Mech. 764 (2015) 349-361, 2018 Results from direct numerical simulations of vertical natural convection at Rayleigh numbers $1.0\times 10^5$-$1.0\times 10^9$ and Prandtl number $0.709$ support a generalised applicability of the Grossmann-Lohse (GL) theory, which was originally developed for horizontal natural (Rayleigh-B{\'e}nard) convection.

Effect of Heat Source Placement on Natural Convection from Cylindrical Surfaces
Energies, 2020 Placement of heat source can play a significant role in final heat output, or heat source effectivity. Because of this, there is a need to analyze thermal fields of the heat exchange system by natural convection, where the description by criterion ...
