چکیده

This article presented an analysis of the pulsatile flow non-Newtonian micropolar (MP) fluid under Lorentz force’s effect in a channel with symmetrical constrictions on walls. The governing equations were first converted into vorticity–stream function form, and finite difference-based solver was used to solve it numerically Cartesian grid. impacts different controlling parameters, including Hartman number, Strouhal Reynolds MP parameter profiles, studied. wall shear stress (WSS), axial, micro-rotation velocity profiles depicted visually. streamlines vorticity patterns also sketched. It is evident from numerical results that separation region near constriction as well flattening axial component effectively controlled by Hartmann number. At maximum rate, WSS attained its peak. increased both number whereas declined higher values parameter. increment

Numerical Simulation of Micropolar Flow in a Channel under Osciatory Pressure Gradient

We numerically investigate the pulsatile flow and heat transfer of a micropolar fluid through a Darcy-Forchhmeir porous channel in the presence of wall transpiration. We use the central difference approximations for the spatial derivatives, whereas the time integration has been performed by employing the three steps explicit Runge-Kutta method to obtain the numerical solution. It i...

MHD Flow of the Micropolar Fluid between Eccentrically Rotating Disks

This analytical investigation examines the magnetohydrodynamic flow problem of an incompressible micropolar fluid between the two eccentrically placed disks. Employing suitable transformations, the flow governing partial differential equations is reduced to ordinary differential equations. An exact solution representing the different flow characteristic of micropolar fluid has been derived by s...

Peristaltic flow of a micropolar fluid in an asymmetric channel

In this paper, we carry out a study of peristaltic motion of an incompressible micropolar fluid in an asymmetric channel. The flow analysis has been developed for low Reynolds number and long wavelength case. Exact analytic solutions have been established for the axial velocity, microrotation component and stream function. Expression for the shear stresses are also obtained. The effects of pert...
