Spectral Jacobi approximations for Boussinesq systems
Studies in Applied MathematicsAbstractThis paper is concerned with the numerical approximation of initial‐boundary‐value problems of a three‐parameter family of Bona–Smith systems, derived as a model for the propagation of surface waves under a physical Boussinesq regime. The work proposed here is focused on the corresponding problem with Dirichlet boundary conditions and its ...

The approximate solutions of nonlinear Boussinesq equation
Journal of Physics: Conference Series, 2016 The homotopy analysis method (HAM) is introduced to solve the generalized Boussinesq equation. In this work, we establish the new analytical solution of the exponential function form. Applying the homotopy perturbation method to solve the variable coefficient Boussinesq equation.

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.

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.

Convection naturelle dans une cavité rectangulaire inclinée de différents rapports de forme
Revue des Énergies Renouvelables, 2016 Dans ce travail, nous étudions numériquement la convection naturelle instationnaire et bidimensionnelle dans une cavité rectangulaire inclinée et chauffée différentiellement. Le nombre de Rayleigh varie entre 103

On the Frequency of Internal Gravity Waves in the Atmosphere: Comparing Theory with Observations
AtmosphereThis paper is devoted to the dynamics of the propagation of non-planetary scale internal gravity waves (IGWs) in the stratified atmosphere. We consider the system of equations describing internal gravity waves in three approximations: (1) the ...

Nihon Kikai Gakkai ronbunshuA magnet placed near the cooling wall excludes hot oxygen, adsorbs cold oxygen, and forms vortices on the surface of the cooling wall, thereby blocking the approach of hot air. Unlike the heat transfer suppression by an adiabatic wall, this heat transfer
