Effects of different shapes of nanoparticles on peristalsis of nanofluid possessing non-isothermal properties

Le résumé fourni par la source

The exploration of various nanoparticles has become a focal point for researchers, driven by its potential applications in both industry and medicine. Nanoparticles can be incorporated in several shapes and sizes, hence this paper examines the nanofluid’s performance in a peristaltic channel under the impact of combined external applied electric and magnetic fields, in addition to thermal radiation and Joule heating effects. The present study also examines the non-isothermal characteristics with no slip convection for four distinct nanoparticles, namely Iron oxide ( F e 3 O 4 ), Copper (Cu), Gold (Au), and Silver (Ag). Shape effects of nanomaterial are also considered. Arising nonlinear system is tackled numerically employing the integrated package NDSolve in Mathematica by the implementation of weaker Reynolds number and long wavelength assumptions. Current findings expose that radiation has a beneficial impact on controlling the velocity and temperature within the channel. Increase in radiation parameter leads to reduce both velocity and temperature by approximately 2 . 39 % and 18 . 18 % respectively. An improvement of up to 2 . 28 % in heat transfer rate can be achieved by utilizing spherical iron oxide nanoparticles for thermal conductivity parameter of range 0 . 00 − 0 . 10 . Furthermore, silver nanoparticles provide better thermal conductivity compared to other nanoparticles.
