Analysis of peristaltic flow of Jeffrey six constant nano fluid in a vertical non-uniform tube

摘要

Peristaltic flow of non-Newtonian nano fluid through a non-uniform surface has been in-vestigated in this paper. The fluid motion along the wall of the surface is caused by the sinusoidal wave traveling with constant speed. The governing equations are converted into cylindrical coordinate system and assuming low Reynolds number and long wave length partial differential equations are simplified. Analytically solutions of the problem are obtained by utilizing the homotopy perturbation method (HPM). In order to insight the impact of embedded parameters on temperature, concentration and velocity some graphs are plotted for different peristaltic waves. At the end, some observations were made from the graphical presentation that velocity, pressure rise and nano particle concentration are increasing function of thermophoresis para-meter N-t while temperature and frictional forces show opposite trend.
