Direct numerical simulations (DNSs) of three-dimensional cylindrical release gravity currents
in a linearly stratified ambient are presented. The simulations cover a range of stratification …

The dynamics of gravity currents propagating beneath intermediate water waves is
investigated in the present study. Laboratory experiments were carried out in a wave flume …

The pathway of dense river inflows into lakes, which affects the lake water quality, is not
accurately predicted by existing models. The pathway of a dense riverine inflow in a lake …

Gravity currents are flows driven by density gradients between two or more contacting fluids
and play a key role in nature and industrial environments via global ocean circulations …

In many natural settings, gravity currents flow over a mobile sediment bed as in fluvial
outflows into lakes and reservoirs or in submarine canyons in coastal regions. We present …

A two-layer miscible displacement of density-matched but viscosity-contrasted fluids through
a channel is numerically investigated in a nonlinear regime. The flow is governed by Navier …

The collision of two counterflowing gravity currents with unequal strengths was investigated
through large-eddy simulations and laboratory experiments. The collisions were initiated by …

This study presents LES results of lock-release propagating gravity current (GC) at the base
of a linearly stratified ambient. The focus of the study is to investigate the effect of ambient …

In recent years, there have been reports of gas leakage accidents during the transportation
of gas tankers in tunnels, potentially leading to destructive explosions. However, the overall …

This work studies the nearshore hydrodynamics of a shallow turbulent flow entering a
laterally unconfined quiescent ambient with a sloping bottom boundary. Examples of such …
