Peristaltic Flow of a Magneto-Micropolar Fluid: Effect of Induced Magnetic Field

Abstract

We carry out the effect of the induced magnetic field on peristaltic transport of anincompressible conducting micropolar fluid in a symmetric channel. The flow analysis has been developed for low Reynolds number and long wavelength approximation. Exactsolutions have been established for the axial velocity, microrotation component, streamfunction, magnetic-force function, axial-induced magnetic field, and current distributionacross the channel. Expressions for the shear stresses are also obtained. The effectsof pertinent parameters on the pressure rise per wavelength are investigated by means ofnumerical integrations, also we study the effect of these parameters on the axial pressuregradient, axial-induced magnetic field, as well as current distribution across the channeland the nonsymmetric shear stresses. The phenomena of trapping and magnetic-force linesare further discussed.
