Boussinesq systems in two space dimensions over a variable bottom for the generation and propagation of tsunami waves

, 2009
Considered here are Boussinesq systems of equations of surface water wave theory over a variable bottom. A simplified such Boussinesq system is derived and solved numerically by the standard Galerkin-finite element method. We study by numerical means the

A Remark on the Regularity Criterion for the 3D Boussinesq Equations Involving the Pressure Gradient

Abstract and Applied Analysis, 2014
We consider the three-dimensional Boussinesq equations and obtain a regularity criterion involving the pressure gradient in the Morrey-Companato space Mp,q. This extends and improves the result of Gala (Gala 2013) for the Navier-Stokes equations.

BOUSSINESQ EQUATIONS IN THIN SPHERICAL DOMAINS

Kyushu Journal of Mathematics, 2005
Summary: The atmosphere is just the incompressible fluid occupying a thin layer around the Earth. It is known that the equations describing its motion are the three-dimensional (3D) incompressible Navier-Stokes equations in thin spherical shells and the validity of the two-dimensional (2D) approximation of flows in thin spherical layers is proved.

Global well-posedness and viscosity vanishing limit of a new initial-boundary value problem on two/three-dimensional incompressible Navier-Stokes equations and/or Boussinesq equations

Communications in Analysis and Mechanics
The global well-posedness theory and viscosity vanishing limit of the initial-boundary value problem on two/three-dimensional (2D/3D) incompressible Navier-Stokes (NS) equations and/or Boussinesq equations with nonlinear boundary conditions are studied ...

Multiple soliton and lump solutions to a variety of novel integrable multi-dimensional Boussinesq-type equations

Alexandria Engineering Journal
Several scientific fields, including mechanical fluids, plasmas, and solids, use higher-dimensional Boussinesq-type equations to model various nonlinear phenomena, such as solitary and shock waves, as well as lump waves.

Blow-Up Criteria for Three-Dimensional Boussinesq Equations in Triebel-Lizorkin Spaces

Discrete Dynamics in Nature and Society, 2012
We establish a new blow-up criteria for solution of the three-dimensional Boussinesq equations in Triebel-Lizorkin spaces by using Littlewood-Paley decomposition.
