Limits of the Oberbeck–Boussinesq approximation in a tall differentially heated cavity filled with water [PDF]
, 2014 The present work assesses the limits of the Oberbeck–Boussinesq (OB) approximation for the resolution of turbulent fluid flow and heat transfer inside a tall differentially heated cavity of aspect ratio G = 6.67 filled with water (Pr = 3.27, Ra = 2.12e11)

Adaptive Numerical Modeling of Tsunami Wave Generation and Propagation with FreeFem++
Geosciences, 2020 A simplified nonlinear dispersive Boussinesq system of the Benjamin–Bona–Mahony (BBM)-type, initially derived by Mitsotakis (2009), is employed here in order to model the generation and propagation of surface water waves over variable bottom.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.Abstract Plume interaction with a forest canopy results in flow features distinct from those in grasslands. Here, we model the turbulence dynamics of a buoyant plume in a homogeneous plant canopy with a crosswind using Large‐Eddy Simulations. As the plume interacts with the crosswind, we observe increased vorticity at the windward and tilted hair‐pin ...

On the convergence rates for the three‐dimensional filtered Boussinesq equations
, 2021 In this paper we consider a LES model for the approximation of large scales of the 3D Boussinesq equations. We analyze the convergence rate, in appropriate norms, of the unique regular weak solution of the regularized Boussinesq equations towards a weak ...

Effect of the Mitral Valve on the Intra Ventricular Hemodynamics
International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 10, October 2026.Patient‐specific Computational Fluid Dynamics was employed to analyze the impact of four distinct mitral valve geometries, varying in area and jet direction, on left‐ventricular flow and overall heart efficiency. The valve design influenced intraventricular vortices, turbulent kinetic energy, and dissipation.

Approximation à la Oberbeck-Boussinesq for fluids with pressure-induced stratified density
, 2020 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.

Engineering Reports, Volume 8, Issue 10, October 2026.A finite element framework is developed to analyze MHD flow and heat transfer in a porous T‐joint cavity under an inclined magnetic field, including viscous dissipation and heat source/sink effects. The model combines domain discretization, mesh refinement, and equation discretization to obtain validated numerical predictions.

Explicit Solutions of a Gravity-Induced Film Flow along a Convectively Heated Vertical Wall
The Scientific World Journal, 2013 The gravity-driven film flow has been analyzed along a vertical wall subjected to a convective boundary condition. The Boussinesq approximation is applied to simplify the buoyancy term, and similarity transformations are used on the mathematical model of

Natural convection flow near a vertical plate that applies a shear stress to a viscous fluid. [PDF]
PLoS ONE, 2013 The unsteady natural convection flow of an incompressible viscous fluid near a vertical plate that applies an arbitrary shear stress to the fluid is studied using the Laplace transform technique. The fluid flow is due to both the shear and the heating of
