Vortex Theory for Two Dimensional Boussinesq Equations

open access: yes, 2020
In this paper, the single center vortex method (SCVM) is extended to find some vortex solutions of finite core size for dissipative 2D Boussinesq equations. Solutions are expanded in to series of Hermite eigenfunctions. After confirmation the convergence

On Schrödinger-Boussinesq equations

open access: yesAdvances in Differential Equations, 2004
We study local and global well-posedness for the initial-value problem associated to the one-dimensional Schrödinger-Boussinesq equations in low regularity spaces. To establish these results we make use of sharp $L^p$-$L^q$ estimates.

Exact Solutions Superimposed with Nonlinear Plane Waves

open access: yesInternational Journal of Differential Equations, 2016
The flow of fluid in atmosphere and ocean is governed by rotating stratified Boussinesq equations. Through the literature, we found that many researchers are trying to find the solutions of rotating stratified Boussinesq equations. In this paper, we have

An incompressible 2D didactic model with singularity and explicit solutions of the 2D Boussinesq equations

open access: yes, 2014
We give an example of a well posed, finite energy, 2D incompressible active scalar equation with the same scaling as the surface quasi-geostrophic equation and prove that it can produce finite time singularities. In spite of its simplicity, this seems to

Evolution of initial discontinuities in the Riemann problem for the Kaup-Boussinesq equation with positive dispersion [PDF]

open access: yes, 2017
We consider the space-time evolution of initial discontinuities of depth and flow velocity for an integrable version of the shallow water Boussinesq system introduced by Kaup.

Global well-posedness for the 2D Boussinesq equations with a velocity damping term [PDF]

open access: yesDiscrete and Continuous Dynamical Systems. Series A, 2017
In this paper, we prove global well-posedness of smooth solutions to the two-dimensional incompressible Boussinesq equations with only a velocity damping term when the initial data is close to an nontrivial equilibrium state $(0,x_2)$.

Bistable Bright-Dark solitary wave solutions of the (3 + 1)-dimensional Breaking soliton, Boussinesq equation with dual dispersion and modified Korteweg–de Vries–Kadomtsev–Petviashvili equations and their applications

open access: yesResults in Physics, 2017
The Boussinesq equation with dual dispersion and modified Korteweg–de Vries–Kadomtsev–Petviashvili equations describe weakly dispersive and small amplitude waves propagating in a quasi three-dimensional media.

Blow-up criterion for the density dependent inviscid Boussinesq equations

open access: yesBoundary Value Problems, 2020
In this work, we consider the density-dependent incompressible inviscid Boussinesq equations in R N ( N ≥ 2 ) $\mathbb{R}^{N}\ (N\geq 2)$ . By using the basic energy method, we first give the a priori estimates of smooth solutions and then get a blow-up ...

Optimal Transport, Convection, Magnetic Relaxation and Generalized Boussinesq equations

open access: yes, 2008
We establish a connection between Optimal Transport Theory and classical Convection Theory for geophysical flows. Our starting point is the model designed few years ago by Angenent, Haker and Tannenbaum to solve some Optimal Transport problems.

Pseudospectral Method for the "Good" Boussinesq Equation [PDF]

open access: yesMathematics of Computation, 1991
The paper deals with the pseudospectral time-discrete method for the ''good'' Boussinesq equation. The difficulties in the study of the stability of the aliasing error in the nonlinear term are removed in a way which is roughly equivalent to the use of negative Sobolev norms. Numerical comparisons with finite difference schemes are also given.
