Gravity currents in a porous medium at an inclined plane
We consider the release from a point source of relatively heavy fluid into a porous saturated medium above an impermeable slope. We consider the case where the volume of the resulting gravity current increases with time like t and show that for α < 3, at short times the current spreads axisymmetrically, with radius r ∼ t, while at long times it spreads predominantly downslope. In particular, fo...

متن کاملThe Density-Driven Nanofluid Convection in an Anisotropic Porous Medium Layer with Rotation and Variable Gravity Field: A Numerical Investigation
In this study, a numerical examination of the significance of rotation and changeable gravitational field on the start of nanofluid convective movement in an anisotropic porous medium layer is shown. A model that accounts for the impact of Brownian diffusion and thermophoresis is used for nanofluid, while Darcy’s law is taken for the porous medium. The porous layer is subjected to uniform rotat...
متن کاملLock-release inertial gravity currents over a thick porous layer
This paper examines the motion of a dense fluid that develops as an inertial gravity current of decreasing mass above a horizontal porous bed, while flow described by Darcy’s law occurs in the bed. Measurements of the mass and the front position of the current in a set of laboratory experiments performed by changing different parameters are presented. The results are explained by means of a glo...
متن کاملMathematical modeling of blood flow in an inclined tapered artery under MHD effect through porous medium
The purpose of this work is to study the effect of blood flow in an inclined tapered artery under MHD effect through porous medium. Blood is considered as an electrically conducting Newtonian fluid. In this model, the analytical expressions for the volumetric flow rate, pressure gradient, wall shearing stress, and velocity profile have been derived. The problem is described by the usual MHD equ...
