The Complex Ginzburg Landau Model for an Oscillatory Convection in a Rotating Fluid Layer

Abstract: A weakly nonlinear thermal instability is investigated under rotation speed modulation. Using the perturbation analysis, a nonlinear physical model is simplified to determine the convective amplitude for oscillatory mode. A non-autonomous complex Ginzburg-Landau equation for the finite amplitude of convection is derived based on a small perturbed parameter. The effect of rotation is found either to stabilize or destabilize the system. The Nusselt number is obtained numerically to present the results of heat tr… Show more

“…Through local nonlinear stability analysis, heat mass transfer was quantified. The effect of internal solutal Rayleigh number and rotation on weakly nonlinear [41][42][43][44][45] thermal instability was studied by Kiran [39] and Kiran and Manjula [40]. The rotation and negative internal solutal Rayleigh number reduce the mass transfer in the system (see: Malkus and Veronis [41]).…”
