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 .
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  applied the same approach to study the heat irreversibility in non-Newtonian fluid flow
Xu, "Deforming-spatial-domain/stabilized space-time (DSD/SST) method in computation of non-Newtonian fluid flow
and heat transfer with moving boundaries," Computational Mechanics, vol.
Kahraman and Yurusoy  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  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.
