On the Use and Misuse of the Oberbeck–Boussinesq Approximation

open access: yesPhysics, 2023
The Oberbeck–Boussinesq approximation is the most commonly employed theoretical scheme for the study of natural or mixed convection flows. However, the misunderstanding of this approximated framework is a possibility that may cause the emergence of ...

Beyond the Oberbeck–Boussinesq and long wavelength approximation [PDF]

open access: yesNuclear Fusion, 2022
We present the first simulations of a reduced magnetized plasma model that incorporates both arbitrary wavelength polarization and non-Oberbeck–Boussinesq effects.

The Boussinesq approximation for buoyant flows

open access: yesMechanics Research Communications, 2022
The aim of this communication is to present a simplified, yet rigorous, deduction of the Boussinesq approximated governing equations for buoyant flows. In order to carry out the core deduction procedure, a simplified version of the manifold asymptotic analyses available in the literature is discussed. The method adopted in this study is focussed on the

Simulation of Low-Speed Buoyant Flows with a Stabilized Compressible/Incompressible Formulation: The Full Navier–Stokes Approach versus the Boussinesq Model

open access: yesAlgorithms, 2022
This paper compares two strategies to compute buoyancy-driven flows using stabilized methods. Both formulations are based on a unified approach for solving compressible and incompressible flows, which solves the continuity, momentum, and total energy ...

Energetics of internal solitary waves in a background sheared current [PDF]

open access: yesNonlinear Processes in Geophysics, 2010
The energetics of internal waves in the presence of a background sheared current is explored via numerical simulations for four different situations based on oceanographic conditions: the nonlinear interaction of two internal solitary waves; an internal ...

Some aspects in Kelvin-Helmholtz instability with and without Boussinesq approximation [PDF]

open access: yesINCAS Bulletin, 2021
The topic of this paper is the Kelvin-Helmholtz instability, a phenomenon which occurs on the interface of a stratified fluid, in the presence of a parallel shear flow, when there is a velocity and density difference across the interface of two adjacent ...

Wave Energy Dissipation of Spilling and Plunging Breaking Waves in Spectral Models

open access: yesJournal of Marine Science and Engineering, 2022
On the basis of field experiments and modeling, the dependence of the dissipation of the energy of waves breaking by plunging and spilling on the frequency of wave spectra was investigated. It was shown that the modeling of wave breaking should take into
