A total of 95 full- and partial-depth lock release experiments were conducted to investigate the qualitative and quantitative properties of gravity current ﬂow over sinusoidal topography in a two-layer ambient. Density differences between ﬂuids are limited to a Boussinesq regime and are...
An experimental study of the shear-induced buckling of a thin, viscous film in an axisymmetric geometry is presented. Rotating the inner boundary relative to a stationary outer one, generates large in-plane shear forces in the laterally constrained millimetric film, which leads to buckling of the...
An algorithm is presented that disentangles the temporal and spatial structure of polychromatic internal wave fields generated through tidal conversion without a-priori knowledge of the topographic details. This spatial structure is relevant in estimating the location of ocean mixing. Using the...
We examine the transient evolution of a negatively buoyant, laminar plume in an emptying filling box containing a uniform porous medium. In the long time limit, τ→∞, the box is partitioned into two uniform layers of different densities. However, the approach towards steady state is characterized...
An analytical and experimental study of boundary gravity currents propagating through a two-layer stratified ambient of finite vertical extent is presented. The theoretical discussion considers slumping, supercritical gravity currents, i.e. those that generate an interfacial disturbance whose...
The time evolution of a two dimensional incompressible, density stratified, Boussinesq flow in a rectangular cavity is numerically simulated for a range of parameters. Boundary control is then implemented along the upper boundary by adjusting the fluid density. More specifically, the top boundary...
Drawing on ideas from turbulent plume theory, a novel solution is presented for buoyant convection from an isolated source in uniform and non-uniform porous media of finite extents. In the former case, the problem is divided into three flow regimes: (i) a negatively-buoyant plume, (ii)...
Buoyancy driven flow between two finite zones containing fluid of slightly different density is investigated. Two zones separated by (i) a single common doorway, and, (ii) top and bottom vents. In the former case, a two-layer exchange flow develops once the barrier is removed. In the zone that...
Consider an open control volume consisting of a porous medium submerged in a surrounding ambient fluid of density ρ_a. The top and bottom of the control volume allow ambient fluid to enter the porous medium. Saline fluid of density ρ_s>ρ_a is supplied at a constant rate of Q_o near the top of the...
Bottom propagating gravity currents resulting from full- and partial-depth lock-release experiments are investigated as they propagate up a rising slope in uniform and two-layer stratified ambients. In the case of uniform ambients, the gravity current front decelerates in a nearly uniform...
