On the sensitivity of 3-D thermal convection codes to numerical discretization: a model intercomparison
numerical discretization 3-D thermal convection codes
2014/12/19
Fully 3-D numerical simulations of thermal convection in a spherical shell have become a standard for studying the dynamics of pattern formation and its stability under perturbations to various parame...
Scaling laws prediction from a solvable model of turbulent thermal convection
Scaling laws solvable model turbulent thermal convection
2011/7/7
A solvable turbulent model is used to predict both the structure of the boundary layer and the scaling laws in thermal convection. The transport of heat depends on the interplay between the thermal, v...
Scaling in large Prandtl number turbulent thermal convection
Scaling Prandtl number thermal convection
2011/7/5
We study the scaling properties of heat transfer Nu in turbulent thermal convection at large
Prandtl number Pr using a quasi-linear theory. We show that two regimes arise, depending on the
Reynolds ...
Polymer heat transport enhancement in thermal convection: the case of Rayleigh-Taylor turbulence
Polymer heat transport thermal convection
2010/4/1
We study the effects of polymer additives on turbulence generated by the ubiquitous Rayleigh-Taylor instability. Numerical simulations of complete viscoelastic models provide clear evidence that the h...
The global characteristics of the three-dimensional thermal convection inside a spherical shell
global characteristics three-dimensional thermal convection spherical shell
2009/11/13
The Rayleigh number-Nusselt number, and the Rayleigh number-thermal boundary layer thickness relationships are determined for the three-dimensional convection in a spherical shell of constant physical...
Gyrostatic extensions of the Howard-Krishnamurti model of thermal convection with shear
Gyrostatic extensions Howard-Krishnamurti model thermal convection
2009/10/30
The Howard & Krishnamurti (1986) low-order model (LOM) of Rayleigh-Bénard convection with spontaneous vertical shear can be extended to incorporate various additional physical effects, such as externa...
