Convection Induced by Inclined Gradients in a Shallow Porous Medium Layer
Краткое описание
A review is made of recent convection studies in a shallow layer of a saturated porous medium, induced by applied thermal and/or solutal gradients. This problem is likely to be paradigmatic for convection induced by such gradients in more general geometries. A horizontal gradient induces a "Hadley circulation," which can be superimposed on any existing forced convection flow. The stability of the combined basic flow depends on the horizontal and vertical components of the inclined gradients. Above a certain vertical gradient value an additional cellular flow is superimposed on the basic flow. The nature of the additional cellular flow (e.g., stationary or oscillatory horizontal rolls whose axes are perpendicular to the vertical gradient and aligned with or perpendicular to the horizontal gradient), depends on the parameters involved.
