Fall 2020
Visible plumes discharged by cooling towers have gained much attention due to their negative aesthetic and environmental impact. To achieve plume abatement, many previous designs mix warm, dry air with the hot, humid air rising from the cooling tower fill in the plenum chamber and thereby...

This thesis describes an investigation of gravity currents, which are buoyancy-driven horizontal fluid flows. In particular this work reports upon a series of laboratory experiments and complementary (two-dimensional) direct numerical simulations that explore the lock release of a fixed volume of...

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...

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 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...

Kattemalalawadi, Bharath S. P.
To improve the confidence of subsurface storage of fluids such as carbon-dioxide, acid-gas and hydrogen at various geological sites, a proper fluid dynamic understanding of flow phenomena occurring because of injecting these source fluids into a porous medium is necessary. While many advancements...

The core annular flow (CAF) theory is used to model the parallel flow of fluids of different phases. CAF theory has been applied to a lot of industrial applications from bitumen hydro transport to sub-aqueous drag reduction. Here we consider the extension of core annular flow theory to the study...

The most practical and economical method of dissipating waste heat from power stations and related heavy industry is via wet cooling towers. These towers dissipate the waste heat present in a stream of hot process water primarily by evaporating some small fraction of this water, which, in turn,...

The effect of buoyant convection on the buoyancy-driven spreading and draining of porous media gravity currents along a permeability jump
DownloadSpring 2022
We investigate theoretically the impact of introducing convective dissolution along the interface of a (dense) miscible gravity current propagating up- and downdip along a permeability jump in a saturated, layered porous medium. Emphasis is placed on three different dissolution scenarios, namely...

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...
