Peristaltic Motion of Nanofluid in a Curved Channel

Abstract

This article describes the peristaltic transport of nanofluids in a curved channel. Transport equations contain the simultaneous effects of Brownian motion and thermophoretic diffusion of nanoparticles. The governing equations are modeled. Mathematical analysis is performed subject to long wavelength and low Reynolds number assumptions. Numerical solutions are obtained by employing shooting method. Results indicate an increase in the pumping rate when the strengths of Brownian motion and thermophoresis effects are increased. It is observed that the profiles of temperature and nanoparticles concentration are not symmetric about the central line of the curved channel which is different from the case of planar channel.

MHD Unsteady Flow of a Williamson Nanofluid in a Vertical Porous Space With Oscillating Wall Temperature

“…Akbar et al (2013) have examined the numerical study of Williamson nanofluid flow in an asymmetric channel. Hina et al (2014) have studied the peristaltic transport of nanofluids in a curved channel with the effects of Brownian motion and thermophoretic diffusion of nanoparticles using long wavelength and low Reynolds number assumptions. Srinivas et al (2014) have presented the flow and thermal analysis of nanofluid in the wavy channel using CFD package assuming single phase approach.…”

Effect of radiation and magnetic field on peristaltic transport of nanofluids through a porous space in a tapered asymmetric channel

“…He noticed that both temperature and nanoparticles volume fraction increase when the Brownian motion and thermophoresis effects intensify. Hina et al [53] described the peristaltic transport of nanofluids in a curved channel. They observed that the profiles of temperature and nanoparticles concentration are not symmetric about the central line of the curved channel which is different from the case of planar channel.…”
