Destabilizing convection using vibration in a rotating porous layer with a stabilizing temperature gradient
2019, International Journal of Heat and Mass TransferCitation Excerpt :Thermo-flow in porous media saturated by a pure fluid and involving rotation has been extensively studied by numerous authors and subject to various boundary conditions. Pioneering work by Vadasz [1–9], presents analytical results for fluid flow and heat transfer in a vertical porous layer subjected to centrifugal acceleration only various locations from the axis of rotation. Vadasz and Govender [10] later included the effects of gravity and discovered that gravity plays a fairly passive role in the stability criteria describing the convection threshold.
Vibration effects on convection in a rotating fluid saturated porous layer distant from the axis of rotation
2019, International Journal of Heat and Mass TransferCitation Excerpt :Fluid flow and heat transfer in porous media saturated by a pure fluid and involving rotation has been extensively studied by numerous authors in various configurations. The pioneering work by Vadasz [1–9], presents analytical results for fluid flow and heat transfer in a vertical porous layer subjected to centrifugal acceleration only, for the porous layer placed at the axis of rotation, distant from the axis of rotation, and far away from axis of rotation. Vadasz and Govender [10] then included the effects of gravity and discovered that gravity plays a fairly passive role in the stability criteria describing the convection threshold.
Effects of centrifugal buoyancy on developing convective laminar flow in a square channel occupied with a high porosity fibrous medium
2015, International Journal of Heat and Mass TransferCitation Excerpt :The data has confirmed the ability of inducing a mainstream flow along the channel by means of the secondary circulation resulting from the locally varying permeability. The natural convection induced by the centrifugal acceleration in a narrow porous layer subjected to rotation was examined analytically by Vadasz [18], Vadasz [19], and Vadasz [20] for an axis of rotation attached to the porous layer, distant from the porous layer, and located within the porous layer, respectively. The results indicated that displacing the porous layer away from the axis of rotation has a destabilizing effect, while placing the rotation axis within the porous layer produces a stabilising influence in the part of the layer located to the left of the axis of rotation and conversely a destabilising effect to the right part of it.
Developing convective flow in a square channel partially filled with a high porosity metal foam and rotating in a parallel-mode
2015, International Journal of Heat and Mass TransferCitation Excerpt :The data has confirmed the ability to induce a mainstream flow along the channel by means of the secondary circulation resulting from a locally varying permeability. Natural convection induced by centrifugal acceleration in a narrow porous layer subjected to rotation was examined analytically by Vadasz [25–27] for an axis of rotation attached to, distant from, and located within the porous layer, respectively. The results indicated that displacing the porous layer away from the axis of rotation has a destabilizing effect that enhances the centrifugal buoyancy.

Natural convection induced by centrifugal acceleration in a narrow porous layer subjected to rotation was examined analytically by Vadasz [12–14] for an axis of rotation attached to, distant from, and located within the porous layer, respectively.
