Peristaltic transport of conducting Williamson fluid in a porous channel

Abstract

In physiology, peristalsis is used to transport the biofluid from a region of lower pressure to higher pressure in the living body. Most of the biofluids (such as blood) are classified as non-Newtonian fluids. In some pathological conditions, the distribution of fatty cholesterol and artery clogging blood clots in the lumen of coronary artery can be modeled as fluid flow in a porous tube. In view of this, the peristaltic flow of a conducting non-Newtonian Williamson fluid in a porous channel with flexible walls under the effects of radiation is investigated. The problem is solved applying perturbation method. Velocity distribution and pressure flow characteristics are calculated and the effects of various emerging parameters on the flow characteristics are discussed in detail.
