Mathematical model for the peristaltic flow of nanofluid through eccentric tubes comprising porous medium

Abstract

Mathematical model for peristaltic flow of nanofluid between eccentric tubes is investigated through a porous medium. Assumptions of long wavelength and low Reynolds number are carried out to observe the intestinal flow. The flow is considered to be unsteady and incompressible. Analytical solutions are evaluated through homotopy perturbation method. The expression of pressure rise is obtained through numerical integration whose data is presented in table. The problems under consideration are made dimensionless to reduce the complication of the analysis and to merge the extra parameters. All the emerging parameters affecting the flow phenomenon are discussed graphically. Trapping bolus scheme is also presented through streamlines for various pertinent quantities.

Analytical and numerical treatment to study the effects of hall currents with viscous dissipation, heat absorpation and chemical reaction on peristaltic flow of Carreau nanofluid

“…A large amount of literature is available which deals with the study of nanofluid and its applications. Nadeem et al [1] have discussed mathematical model for the peristaltic flow of nanofluid through eccentric tubes comprising porous medium. Eldabe et al [2] have investigated the peristaltic transport of manetohydrodynamic Carreau nanofluid with heat and mass transfer inside asymmetric channel.…”

New Insight into AuNP Applications in Tumour Treatment and Cosmetics through Wavy Annuli at the Nanoscale

“…Later, Nadeem et al . 15 used the homotopy perturbation technique to investigate the peristalsis of an incompressible nanofluid in the porous region of a vertical annulus; equations were derived and solved with a low Reynolds number and long wavelength approximation. The researchers concluded that the peristaltic pumping rate increases as the local NP Grashof number is increased.…”

“…Often, the heating effect in metallic NPs is amplified in the presence of electromagnetic radiation 19 . Moreover, the combination of magnetic fields with peristaltic flows has significant applications in biomedical engineering problems 11,15–18,20,23–28 . Abdelsalam and Vafai 29 investigated the magnetohydrodynamic peristaltic flow of a non-Newtonian fluid in the porous space of a microchannel.…”
