Entrainment of ambient fluid into both two-dimensional and axisymmetric gravity currents is investigated experimentally using a novel neutralization technique. The technique involves the titrative neutralization of an alkaline gravity current which intrudes into and entrains an acidic ambient, and is visualized using a pH indicator solution. Using this technique, we can determine quantitative results for the amount of dilution in the head of the current. The head of the current is able to… 

Entraining gravity currents

Abstract Entrainment of ambient fluid into a gravity current, while often negligible in laboratory-scale flows, may become increasingly significant in large-scale natural flows. We present a

Mixing in axisymmetric gravity currents

We present new experiments to measure the rate of entrainment of ambient fluid into a high Reynolds number, axisymmetric, turbulent gravity current. The current is produced by the rapid release of a

Gravity currents: entrainment, stratification and self-similarity

We present new experiments of the motion of a turbulent gravity current produced by the rapid release of a finite volume of dense aqueous solution from a lock of length $L$ into a channel $x>0$

Turbulent entrainment into fluid mud gravity currents

The entrainment of ambient water into non-Newtonian fluid mud gravity currents was investigated in this study. Constant volume release gravity currents were generated in a lock-exchange tank for a

In light of previous numerical studies demonstrating a strong sensitivity of the strength of thermohaline circulation to the representation of overflows in ocean general circulation models, the

Role of head of turbulent 3-D density currents in mixing during slumping regime

A fundamental study was conducted to shed light on entrainment and mixing in buoyancy-driven Boussinesq density currents. Large-eddy simulation was performed on lock-exchange (LE) release density

Vortical structures, entrainment and mixing process in the lateral discharge of the gravity current

Lateral gravity currents can play a critical role in the exchange of materials between terrestrial and marine ecosystems. The three-dimensional flow structure and mixing process of the gravity

Entrainment and mixing in unsteady gravity currents

ABSTRACT Entrainment and mixing in lock-exchange gravity currents are investigated by large eddy simulations. Nine cases are analysed, varying the initial excess density driving the motion and the

Propagation of a gravity current in a two‐layer stratified environment

[1] Gravity currents are created by a continuous release of dense fluid along a 6° inclined ramp. The surrounding fluid is composed of a two-layer stably stratified environment. A chemical



Entrainment in turbulent gravity currents

LABORATORY gravity currents are frequently used to model a range of environmental and industrial flows1. The manner in which these flows become diluted with distance by the surrounding fluid has

The slumping of gravity currents

Experimental results for the release of a fixed volume of one homogeneous fluid into another of slightly different density are presented. From these results and those obtained by previous

Experiments on the dynamics of a gravity current head

Some of the dense fluid at the front of an advancing gravity current is observed to be mixed with the ambient fluid. This process continues when the cross-stream non-uniformities at the head of the

Gravity currents created by the release of a fixed volume of a suspension into a lighter ambient fluid are studied theoretically and experimentally. The greater density of the current and the
