英文摘要	Thermal convection driven by centrifugal buoyancy in a rotating porous cylindrical annulus with conical end boundaries is investigated. The Darcy-Brinkman model with the addition of the time-derivative and Coriolis terms in a rotating frame of reference is applied to characterize the flow in porous media. The effects of the Darcy number and the Coriolis parameter on the thermal convective instability are analyzed by conducting linear stability analysis. Based on weakly nonlinear analysis, the Nusselt number is analytically determined in the neighborhood of onset points. The time evolution of convection patterns and the Nusselt number at high Rayleigh numbers are numerically simulated with the Galerkin method. Especially, the Nusselt number in the stage of stationary, time-periodic, and chaotic convection is obtained in our numerical simulation. (C) 2013 AIP Publishing LLC.
