Peristaltic Transport of Hyperbolic Tangent Fluid in a Tapered Asymmetric Channel

Abstract

Objectives:The study intends to investigate the problem of peristalsis transport of hyperbolic tangent fluid in a tapered asymmetric channel. Methods: The two-dimensional equations of a hyperbolic tangent fluid have been simplified under the suspicions of low Reynolds number and long wavelength approximations. The reduced equations are solved by using standard perturbation technique. The numerical results obtained are presented in the graphical form for various values of physical parameters and are discussed. Findings: It is showing that for the larger values of non-uniform parameter, pressure rise diminishes and the axial velocity diminishes at the core part of the channel and increases at the right and left side of the channel for the increasing values of non-uniform parameter. Applications: Hyperbolic tangent fluid model anticipate the shear thinning phenomenon very accurately and are being used mostly in laboratory experiments and industries.
