A novel approach of the conformal mappings with applications in biotribology

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In this paper, the flow of an incompressible non Newtonian fluid between two eccentric cylinders is considered. The aim of this study is to determine the flow in the case of the stationary movement of some viscous fluids between two eccentric cylinders ...

A counterexample to the smoothness of the solution to an equation arising in fluid mechanics [PDF]

, 2002
We analyze the equation coming from the Eulerian-Lagrangian description of fluids. We discuss a couple of ways to extend this notion to viscous fluids. The main focus of this paper is to discuss the first way, due to Constantin.

Asymptotic analysis of Leray solution for the incompressible NSE with damping

Demonstratio Mathematica
In 2008, Cai and Jiu showed that the Cauchy problem of the Navier-Stokes equations, with damping α∣u∣β−1u\alpha {| u| }^{\beta -1}u for α>0\alpha \gt 0 and β≥1\beta \ge 1 has global weak solutions in L2(R3){L}^{2}\left({{\mathbb{R}}}^{3}).

Extension of a discontinuous Galerkin finite element method to viscous rotor flow simulations [PDF]

, 2005
Heavy vibratory loading of rotorcraft is relevant for many operational aspects of helicopters, such as the structural life span of (rotating) components, operational availability, the pilot's comfort, and the effectiveness of weapon targeting systems.

Maximal Lp -Lq regularity to the Stokes problem with Navier boundary conditions

Advances in Nonlinear Analysis, 2017
We prove in this paper some results on the complex and fractional powers of the Stokes operator with slip frictionless boundary conditions involving the stress tensor.

Attractors for a deconvolution model of turbulence [PDF]

arXiv, 2008
We consider a deconvolution model for 3D periodic flows. We show the existence of a global attractor for the model.

Regularity criteria in weak spaces for Navier-Stokes equations in R3 [PDF]

arXiv, 2006
In this paper we establish a Serrin type regularity criterion on the gradient of pressure in weak spaces for the Leray-Hopf weak solutions of the Navier-Stokes equations in R3.

Global regularity for the 3D Navier-Stokes and the 3D Euler equations [PDF]

arXiv, 2007
The article `Global regularity for the 3D Navier-Stokes and the 3D Euler equations'(arXiv:0711.2453) is withdrawn due to a serious error in the proof.

On the a priori estimates for the Euler, the Navier-Stokes and the quasi-geostrophic equations [PDF]

arXiv, 2007
We prove new \emph{a priori} estimates for the 3D Euler, the 3D Navier-Stokes and the 2D quasi-geostrophic equations by the method of similarity transforms.
