Effect of rotation on the onset of Rayleigh-Bénard convection in a layer of Ferrofluid
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
The effect of rotation on the Rayleigh-Bénard convection in a horizontal layer of ferrofluid is investigated by using Galerkin weighted residuals method. Linear stability theory based upon normal mode analysis and perturbation method is used to find expressions for Rayleigh number for free-free boundary layer of fluid. It is observed that the system is more stable in the rotating fluid than non-rotating fluid layer. ‘Principle of exchange of stabilities’ not valid and theoscillatory convection is possible only for certain conditions. The effect of rotation and magnetic parameters on the stationary convection is investigated analytically.
