Effect of Magnetic Field and Porosity on Peristaltic Flow of Micropolar Fluid

Abstract

In this paper, the peristaltic flow of micropolar fluid in a flexible tube with viscoelastic is studied under effect of magnetic field and porosity. The Runge-Kutta method is used to solve the governing equations of motion resulting from a perturbation technique for small values of amplitude ratio. The time mean axial velocity profiles are presented for the case of free pumping and analyzed to observe the influence of porosity and magnetic field for various values of radial r and wave numbe. The numerical results of the time mean velocity profile are discussed in detail for homogeneous fluid under effect of magnetic field and porosity for different cases by figures. The results indicate that the effect of porosity and magnetic field are very pronounced. Numerical results are given and illustrated graphically.
