Effect of Magnetic Field on Newtonian Fluid Sandwiched Between Non-Newtonian Fluids Through Porous Cylindrical Shells

Abstract

The present work deals with the influence of magnetic field on Newtonian fluid sandwiched between two porous cylindrical pipes which are filled with micropolar fluids. Fluid motion is occurring along z * -axis and applied magnetic field is taken in the direction perpendicular to the direction of fluid motion. On applying appropriate boundary conditions, velocity profiles, microrotations, flow rate and shear stresses are obtained for the corresponding fluid regions. The graphs for volumetric flow rate and fluid velocity are plotted and discussed for different values of micropolar parameter, couple stress parameter, porosity, viscosity ratio parameter, Hartmann number, conductivity ratio parameters and Darcy numbers.

Role of electromagnetic analysis in radiative immiscible Newtonian and non‐Newtonian fluids through a microchannel with chemical reactions

“…Jaiswal and Yadav 44 studied the immiscible non‐Newtonian micropolar and Newtonian fluids in a porous horizontal channel with the effect of an inclined magnetic field and observed that shearing stress enhances with the increase in Hartmann number and viscosity ratio. Maurya and Deo 45 investigated the influence of a magnetic field on two immiscible fluids which are sandwiched between two porous cylindrical pipes and observed that fluid velocity decreases with the Hartmann number. Yadav and Verma 46 examined the immiscible non‐Newtonian micropolar fluid and Newtonian fluid in a porous cylindrical pipe and concluded that the velocity of the immiscible fluids decreases with the permeability parameters.…”

Hydromagnetic Flow of Casson Fluid Over a Stretching Plane Through Porous Medium

“…Deo and Maurya [26] reported the drag for flow of micropolar liquid through a porous cylinder which is embedded in another infinite porous medium. Recently, Maurya and Deo [27] discussed the graphical behaviours of volumetric flow rate and fluid velocity for the problem of MHD effects on Newtonian fluid which is sandwiched between two coaxial porous pipes which are filled with non-Newtonian liquids.…”
