Abstract: In this paper, we have discussed the entropy generation on the ciliary motion of the peristaltic transport of fluids in human body. On the basis of the mathematical model of the copper nanofluids with pure water as the base fluid, the complete problem is analysed under the presence of heat transfer. It is considered that a group of cilia operate together and produce metachronal waves to transport the fluid. The governing flow equations are non-linear partial differential equations, which are reduced to ordinary differential equation form using the dimensionless variables. The investigation is carried out under the assumptions of low Reynold's number and long wavelength. Exact solutions of the fluid velocity, pressure gradient and temperature profile have been obtained. The obtained expressions are then described through graphs for various relevant parameters. Trapping phenomenon for nanoparticle volume fraction is presented at the end of the paper.
