Effect of Variable Viscosity on the Peristaltic Motion of a Jeffrey Fluid in a Symmetric Channel

Peristaltic Transport of a Casson Fluid in a Channel with Permeable Walls

Peristaltic transport of a Casson fluid in a channel with permeable walls is investigated. Exact analytical solution of the flow quantities are developed under long wavelength and low Reynolds number assumptions. The effects of Darcy number and yield stress on the pumping characteristics are obtained and discussed. It is observed that for a given ∆P , the flux Q̄ decreases with increasing Darcy ...

Peristaltic motion of a Carreau fluid in an asymmetric channel

Peristaltic transport of a fluid in channels has been a subject of great interest for the last four decades. Such interest is motivated by several applications of peristaltic flows in engineering and industry. In animals and human bodies, the physiological fluids pumped by the muscular oscillations which correspond to peristaltic activity. In particular, the flow of blood through arteries and v...

Peristaltic Viscoelastic Fluid Motion in a Tube

Peristaltic motion of viscoelastic incompressible fluid in an axisymmetric tube with a sinusoidal wave is studied theoretically in the case that the radius of the tube is small relative to the wavelength. Oldroyd flow has been considered in this study and the problem is formulated and analyzed using a perturbation expansion in terms of the variation of the wave number. This analysis can model t...

Heat and Mass Transfer Analysis on MHD Peristaltic Prandtl Fluid Model through a Tapered Channel with Thermal Radiation

This paper deals with a theoretical investigation of heat and mass transfer with thermal radiation analysis on hydromagnetic peristaltic Prandtl fluid model with porous medium through an asymmetric tapered vertical channel under the influence of gravity field. Analytical results are found for the velocity, pressure gradient, pressure rise, frictional force, temperature and concentration. The in...
