Blow-up criterion of smooth solutions for magneto-micropolar fluid equations with partial viscosity

open access: yesBoundary Value Problems, 2011
In this paper, we investigate the Cauchy problem for the incompressible magneto-micropolar fluid equations with partial viscosity in ℝn(n = 2, 3). We obtain a Beale-Kato-Majda type blow-up criterion of smooth solutions. MSC (2010): 76D03; 35Q35.

Regularity for 3-D MHD Equations in Lorentz Space $L^{3,∞}$

open access: yesCommunications in Mathematical Research, 2023
The regularity for 3-D MHD equations is considered in this paper, it is proved that the solutions (v,B,p) are Hölder continuous if the velocity field v∈L∞(0,T;L x (R 3)) with local small condition r ∣∣ { x∈Br(x0) : |v(x,t0)|> εr −1 ∣∣≤ ε and the magnetic

Zero Viscosity-Diffusivity Limit for the Incompressible Boussinesq Equations in Gevrey Class

open access: yesCommunications in Mathematical Research, 2022
In this paper, we study the zero viscosity-diffusivity limit for the incompressible Boussinesq equations in a periodic domain in the framework of Gevrey class. We first prove that there exists an interval of time, independent of the viscosity coefficient

Remark on the Lifespan of Solutions to 3-D Anisotropic Navier Stokes Equations

open access: yesCommunications in Mathematical Research, 2020
The goal of this article is to provide a lower bound for the lifespan of smooth solutions to 3-D anisotropic incompressible Navier-Stokes system, which in particular extends a similar type of result for the classical 3-D incompressible Navier-Stokes ...

Log Improvement of the Prodi-Serrin Criteria for Navier-Stokes Equations [PDF]

open access: yes, 2007
This article is devoted to a Log improvement of Prodi-Serrin criterion for global regularity to solutions to Navier-Stokes equations in dimension 3. It is shown that the global regularity holds under the condition that |u|/(log(1+|u|)) is integrable in ...

Existence of optimal boundary control for the Navier-Stokes equations with mixed boundary conditions [PDF]

open access: yes, 2015
Variational approaches have been used successfully as a strategy to take advantage from real data measurements. In several applications, this approach gives a means to increase the accuracy of numerical simulations.

Norm inflation for generalized magneto-hydrodynamic system [PDF]

open access: yes, 2015
We consider the three-dimensional incompressible magneto-hydrodynamic system with fractional powers of the Laplacian. We discover a wide range of spaces where the norm inflation occurs and hence small initial data results are out of reach.

Stability of weak solutions for the large-scale atmospheric equations

open access: yesJournal of Inequalities and Applications, 2014
In this paper, we consider the Navier-Stokes equations and temperature equation arising from the evolution process of the atmosphere. Under certain assumptions imposed on the initial data, we show the L1-stability of weak solutions for the atmospheric ...
