Effect of Anisotropy on Stability of Convection in a Rotating Porous Layer Distant from the Center of Rotation
要約
We investigate Rayleigh-Benard convection in an anisotropic porous layer subjected to centrifugal body forces and offset from the center of rotation. The Darcy model (including centrifugal and permeability anisotropy effects) and a modified energy equation (including the effects of thermal anisotropy) are used in the current analysis. The linear stability theory is used to evaluate the critical Rayleigh numbers (one for porous layers placed close to the center of rotation and the other for porous layers placed far away from the center of rotation) for the onset of convection in the presence of thermal and mechanical anisotropy. It is found that the convection is stabilized when the thermal anisotropy ratio (which is a function of the thermal and mechanical anisotropy parameters) is increased in magnitude.
