A stochastic Lagrangian representation of the 3-dimensional incompressible Navier-Stokes equations [PDF]

open access: yes, 2006
In this paper we derive a representation of the deterministic 3-dimensional Navier-Stokes equations based on stochastic Lagrangian paths. The particle trajectories obey SDEs driven by a uniform Wiener process; the inviscid Weber formula for the Euler ...

Numerical studies of viscous incompressible flow between two rotating concentric spheres

open access: yesJournal of Applied Mathematics, Volume 2004, Issue 2, Page 91-106, 2004., 2004
The problem of determining the induced steady axially symmetric motion of an incompressible viscous fluid confined between two concentric spheres, with the outer sphere rotating with constant angular velocity and the inner sphere fixed, is numerically investigated for large Reynolds number.

Effects of the porous boundary and inclined magnetic field on MHD flow in a rectangular duct

open access: yesJournal of Applied Mathematics and Computational Mechanics, 2020
In this work, a steady two dimensional MHD flow of a viscous incompressible fluid through a rectangular duct under the action of an inclined magnetic field with a porous boundary has been investigated.

An indirect boundary integral method for an oscillatory Stokes flow problem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 47, Page 2961-2976, 2003., 2003
The purpose of this paper is to present an indirect boundary integral method for the oscillatory Stokes flow provided by the translational oscillations of two rigid spheres in an incompressible Newtonian fluid of infinite expanse.

Unsteady stagnation point flow of a non‐Newtonian second‐grade fluid

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 60, Page 3797-3807, 2003., 2003
The unsteady two‐dimensional flow of a viscoelastic second‐grade fluid impinging on an infinite plate is considered. The plate is making harmonic oscillations in its own plane. A finite difference technique is employed and solutions for small and large frequencies of the oscillations are obtained.

Asymptotic stability of Landau solutions to Navier-Stokes system [PDF]

open access: yes, 2011
It is known that the three dimensional Navier-Stokes system for an incompressible fluid in the whole space has a one parameter family of explicit stationary solutions, which are axisymmetric and homogeneous of degree -1.

Heat and mass transfer flow of nanofluids in presence of chemical reaction with partial slip conditions

open access: yes, 2020
A mathematical model is presented for analyzing the convective fluid over a stretching surface in the presence of nanoparticles. The analysis of heat and mass transfer of converted fluid with slip boundary condition is investigated.

Feedback stabilization of semilinear heat equations

open access: yesAbstract and Applied Analysis, Volume 2003, Issue 12, Page 697-714, 2003., 2003
This paper is concerned with the internal and boundary stabilization of the steady‐state solutions to quasilinear heat equations via internal linear feedback controllers provided by an LQ control problem associated with the linearized equation.

Numerical investigation on the effects of obstruction and side ratio on non-Newtonian fluid flow behavior around a rectangular barrier

open access: yesJournal of Applied Mathematics and Computational Mechanics, 2019
In this paper, the characteristics of the flow and forced heat transfer of power law non-Newtonian fluids that flow around a quadrilateral and rectangular cylinder that are located in a 2D channel are investigated by use of the finite volume method (FVM)
