Stagnation‐point flow of the Walters′ B′ fluid with slip
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 61, Page 3249-3258, 2004., 2004 The steady two‐dimensional stagnation point flow of a non‐Newtonian Walters′ B′ fluid with slip is studied. The fluid impinges on the wall either orthogonally or obliquely. A finite difference technique is employed to obtain solutions.

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

Numerical studies of viscous incompressible flow between two rotating concentric spheres
Journal 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.

An indirect boundary integral method for an oscillatory Stokes flow problem
International 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.

Approximation of feedback gains for the Oseen system
2000 MSC: 93B52, 65N30, 65N15, 76D55, 76D05, 35Q35We consider the Oseen system with a Dirichlet boundary control, and its semidiscrete approximation by a finite element method (FEM).

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

Feedback stabilization of semilinear heat equations
Abstract 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.

Ergodicity of stochastically forced large scale geophysical flows
International Journal of Mathematics and Mathematical Sciences, Volume 28, Issue 6, Page 313-320, 2001., 2001 We investigate the ergodicity of 2D large scale quasigeostrophic flows under random wind forcing. We show that the quasigeostrophic flows are ergodic under suitable conditions on the random forcing and on the fluid domain, and under no restrictions on viscosity, Ekman constant or Coriolis parameter.
