Peristaltic Transport of Micropolar Fluid in a Tubes Under Influence of Magnetic Field and Rotation
In this paper, The peristaltic flow of micropolar fluid in a flexible tube with viscoelastic is studied under effect of magnetic field and rotation. 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 rotation 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 rotation for different cases by figures. The results indicate that the effect of rotation and magnetic field are very pronounced. Numerical results are given and illustrated graphically.

Peristaltic flow of viscoelastic fluid with fractional Maxwell model through a channel
The paper presents the transportation of viscoelastic fluid with fractional Maxwell model by peristalsis through a channel under long wavelength and low Reynolds number approximations. The propagation of wall of channel is taken as sinusoidal wave propagation (contraction and relaxation). Homotopy perturbation method (HPM) and Adomian decomposition method (ADM) are used to obtain the analytical approximate solutions of the problem. The expressions of axial velocity, volume flow rate and pressure gradient are obtained. The effects of fractional parameters (@a), relaxation time (@l"1) and amplitude (@f) on the pressure difference and friction force across one wavelength are calculated numerically for different particular cases and depicted through graphs.
