On the Use and Misuse of the Oberbeck–Boussinesq Approximation [PDF]
Physics, 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 ...

The Boussinesq approximation for buoyant flows [PDF]
Mechanics 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

Beyond the Oberbeck–Boussinesq and long wavelength approximation [PDF]
Nuclear 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 Oberbeck–Boussinesq approximation in critical spaces [PDF]
Asymptotic Analysis, 2013 In this paper we study the validity of the so-called Oberbeck–Boussinesq approximation for compressible viscous perfect gases in the whole three-dimensional space. Both the cases of fluids with positive heat conductivity and zero conductivity are considered.

A Numerical Method for Extended Boussinesq Shallow-Water Wave Equations [PDF]
, 1999 The accurate numerical simulation of wave disturbance within harbours requires consideration of both nonlinear and dispersive wave processes in order to capture such physical effects as wave refraction and diffraction, and nonlinear wave interactions ...

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 incompressible, in the sense that the density of the fluid is constant.

The Oberbeck–Boussinesq approximation and Rayleigh–Bénard convection revisited
Discrete and Continuous Dynamical SystemsWe consider the Oberbeck--Boussinesq approximation driven by an inhomogeneous temperature distribution on the boundary of a bounded fluid domain. The relevant boundary conditions are perturbed by a non--local term arising in the incompressible limit of the Navier--Stokes--Fourier system.

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

Algorithms, 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 ...
