In the Bingham fluid equations, we take [mu] = 1 and ts = 1.
In this paper we have introduced a new way of solving the linear systems obtained by linearizing and discretizing the non-regularized Bingham fluid flow equations in the augmented formulation.

Numerical results exhibit robustness and scalability of the solver with respect to the mesh size, demonstrating that the proposed method can be used for the accurate simulation of non-regularized Bingham fluids.
The Bingham fluid flow between two permeable beds is discussed by Goverdhan et al.
11] studied the free surface flow of a Bingham fluid in an inclined channel over a permeable bed.
The problem of rotational motion of a Bingham fluid in the gap between two coaxial cylinders, the outer one being at rest and the inner one moving at given angular velocity is solved by Comparini .
Narahari  discussed unsteady flow of a Bingham fluid between two permeable beds having different permeabilities.
14] made a detailed study on the Bingham fluid flow in an inclined channel bounded by two permeable beds.
In this chapter, we modelled the MHD peristaltic flow of a Bingham fluid
through a porous medium in an inclined channel under assumptions of low Reynolds number and long wavelength.
As the constant time m is related to the particles concentration C in the carrier fluid, we can say according to the figure 5, that the paraffin slurry behaves as Newtonian fluid for low concentration values and as a Bingham fluid
for higher values.
