Coherent structures in boundary layers of Rayleigh-Benard convection

open access: yes, 2004
A coherent structure is revealed experimentally by a dyeing technique in the boundary layer of Rayleigh-Benard convection in water. Dye accumulates in streaks aligned with the mean flow.

Numerical Study of Rotating Thermal Convection on a Hemisphere

open access: yesFluids, 2020
Numerical simulations of rotating two-dimensional turbulent thermal convection on a hemisphere are presented in this paper. Previous experiments on a half soap bubble located on a heated plate have been used for studying thermal convection as well as the

Conditional and unconditional nonlinear stability in fluid dynamics [PDF]

open access: yes, 2002
In this thesis we examine some of the interesting aspects of stability for some convection problems. Specifically, the first part of the thesis deals with the Bénard problem for various Non-Newtonian fluids, whereas the second part develops a stability ...

Instability of Two-Layer Rayleigh-Benard Convection with Interfacial Thermocapillary Effect

open access: yes, 2004
The linear instability analysis of the Rayleigh-Allarangoni-Benard convection in a two-layer system of silicon oil 10cS and fluorinert FC70 liquids are performed in a larger range of two-layer depth ratios H, from 0.2 to 5.0 for different total depth H ...

Oscilatory Instability of Rayleigh-Marangoni-Benard Convection in Two-Layer System

open access: yes, 2004
The convective instabilities in two or more superposed layers heated from below were studied extensively by many scientists due to several interfacial phenomena in nature and crystal growth application.

Information Preservation Modeling of Rayleigh-Benard Transition from Thermal Conduction to Convection

open access: yes, 2009
Onset and evolution of the Rayleigh-Benard (R-B) convection are investigated using the Information Preservation (IP) method. The information velocity and temperature are updated using the Octant Flux Splitting (OFS) model developed by Masters & Ye based ...
