TL;DR

This study investigates how nanoparticle shape and Joule heating influence peristaltic water-based copper oxide flow in an asymmetric channel with slip effects, relevant to biomedical and industrial applications.

Contribution

It introduces a semi-analytical approach to analyze nanoparticle shape effects on peristaltic flow considering Joule heating and slip conditions, which is novel in this context.

Findings

Joule heating increases fluid temperature and decreases nanoparticle concentration.

Different nanoparticle shapes have varying thermal conductivities, with lamina shapes being most conductive.

Nanoparticle shape significantly affects velocity, pressure, and temperature distributions.

Abstract

This research paper is intended to study the nanoparticles shapes on peristalsis of Casson fluid in a channel flow by considering Joule heating effects. The study of such flows has various relevance applications in biomedical engineering and industries. Slip conditions is maintained at the velocity, temperature and nanoparticle concentration. The problem is modeled in terms of partial differential equations with suitable slip boundary conditions and then computed by using semi analytical technique known as Homotopy Analysis Method with Mathematica software. The influences of nanoparticles shape on velocity, pressure, temperature and nanoparticle concentration distributions are discussed with the help of graphs. Here, increase in Joule heating parameter enhance the fluid temperature and nanoparticle concentration decreases with an increasing Joule heating and also we observed that the different shapes has different thermal conductivity, but the lamina shaped nanoparticles have high thermal conductivity as compared to needle shaped nanoparticles.
