A numerical investigation of constant-volume non-Boussinesq density currents [PDF]

, 2010
The time-dependent behaviour of non-Boussinesq high-Reynolds-number density currents of density ρc, released from a lock of height h₀ and length x₀ into a ambient of height H and density ρₐ, is considered. We use two dimensional Navier-Stokes simulations

Approximation à la Oberbeck-Boussinesq for fluids with pressure-induced stratified density

, 2021
We consider a model for convection in compressible fluids in two dimensions. A constitutive limit is studied in which both the mechanical compressibility and thermal expansion affect the buoyancy force.

NORi: An ML‐Augmented Ocean Boundary Layer Parameterization

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract NORi is a machine learning (ML) parameterization of ocean boundary layer (BL) turbulence that is physics‐based and augmented with neural networks. NORi stands for neural ordinary differential equations Richardson number (Ri) closure. The physical parameterization is controlled by a Richardson number‐dependent diffusivity and viscosity.

Rational derivation of the Boussinesq approximation

, 2019
This note derives the Boussinesq approximation in a manner consistent with the conservation law of mass. It is shown that the governing equations of a fluid under the approximation can be obtained on the basis of the assumption that the fluid is ...

Irreversible Stirring and Mixing of Tracers by Oceanic Internal Gravity Waves

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract Oceanic internal waves are often thought to be ineffective in stirring and mixing tracer fields such as heat, salt, carbon, and other nutrients. Due to their oscillatory nature, waves are expected to merely displace tracers periodically around their mean position.

Heat Convection of Compressible Viscous Fluids. I. [PDF]

, 2012
The stationary problem for the heat convection of compressible fluid is considered around the equilibrium solution with the external forces in the horizontal strip domain z_0 < z < z_0 + 1 and it is proved that the solution exists uniformly with

Couette-Hiemenz exact solutions for the steady creeping convective flow of a viscous incompressible fluid with allowance made for heat recovery

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2018
In this paper, we study the steady creeping convective flow of a viscous incompressible fluid in the thin infinite layer. The study of the fluid flow is based on the exact solutions class for the Oberbeck-Boussinesq equations in the Stokes approximation ...

High‐Resolution Dynamical Downscaling Refines the Time of Emergence of Sea Level Rise in the Northwestern Pacific

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Sea‐level rise is a major consequence of anthropogenic climate change, yet the timing when regional sea‐level change becomes detectable above natural variability depends on internal ocean dynamics. Most estimates of the time of emergence (ToE) rely on coarse‐resolution global climate models (GCMs), which may underestimate mesoscale and ...

Submarine Landslides Could Cause Wide‐Spread Tsunami Impact in the East Sea (Sea of Japan)

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The East Sea (Sea of Japan) is a seismically active back‐arc basin with a history of devastating tsunamis, yet regional hazard assessments and mitigation planning often overlook the tsunamigenic potential of submarine landslides. This study investigates the tsunami impact of large‐scale mass failures along the southwest (SW) margin of the East
