This section presents numerical simulation of particle movement and turbulence
non-Newtonian fluid flow. The simulation of discrete particles is carried out using the discrete element method.
In contrast little information is available on the suppression of
Non-Newtonian fluid flow separation around a confined square cylinder by superimposed thermal buoyancy.
Lie Group Analysis of a
Non-Newtonian Fluid Flow over a Porous Surface [7].
Within the last thirty years, the study of
non-Newtonian fluid flow over a stretching surface has received significant attention due to its industrial applications.
Kahraman and Yuriisoy [4] applied the same approach to study the heat irreversibility in
non-Newtonian fluid flow through pipes.

non-Newtonian fluid flow and heat transfer with moving boundaries," Computational Mechanics, vol.
Kahraman and Yurusoy [16] examined the entropy generation due to
non-Newtonian fluid flow in an annular pipe with relative rotation using a third-grade fluid model while Chauhan and Kumar [17] presented a non-Newtonian third-grade fluid flow in an annulus partially filled by a porous medium of very small permeability and many more results on entropy generation in literature.
Fluid flow in annular spaces has received great attention from the oil industry, as engineers routinely encounter Newtonian and
non-Newtonian fluid flow through the annulus in both drilling and workover operations.
We have developed a numerical algorithm based on 2D/3D finite element method for solving
non-Newtonian fluid flow with the moving free surface encountered in polymer processing.
Due to its interesting mathematical properties and huge number of applications, the problem of
non-Newtonian fluid flow has attracted attention from a large number of researchers.
Dodge and Metzner [2] proposed a generalized Reynolds number, [bar.Re] , equation for purely viscous
non-Newtonian fluid flow through pipes.
[3] conducted a numerical study of
non-Newtonian fluid flow and heat transfer in tangential and self-wiping co-rotating twin screw extruders with finite difference and finite element methods.
