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

The effect of controlled vibrations on Rayleigh-Benard convection
Journal of Physics: Conference Series, 2021 Abstract The paper presents the results of a numerical study of convective heat transfer in a long horizontal layer heated from below with and without the vibration effect of the lower wall. The simulation was carried out on the basis of solving the Navier-Stokes 2D equations for an incompressible fluid in the Boussinesq approximation ...

Unsteady Heating of Rayleigh-Benard Convection
Zeitschrift für Naturforschung A, 2004 The linear thermal instability of a horizontal fluid layer with time-periodic temperature distribution is studied with the help of the Floquet theory. The time-dependent part of the temperature has been expressed in Fourier series. Disturbances are assumed to be infinitesimal. Only even solutions are considered.
