Hall current and Joule heating effects on peristalsis of TiO2–Ag/EG hybrid nanofluids via a curved channel with heat transfer

Abstract

Hybrid nanofluids have attracted the attention of researchers due to their high heat transfer rates and improved thermal efficiency compared to conventional nanofluids. Outstanding features of hybrid nanofluids make them useful in electronic appliances, transport industry, drug delivery, and so on. Keeping such importance of hybrid nanofluids in mind, goal of this study is to evaluate the Hall currents and Ohmic heating effects on peristalsis of hybrid nanofluids with viscous dissipation and velocity slip effects via a curved channel. Further convective boundary conditions have been considered to aid heat transfer performance. Lubrication approximation is utilized in the mathematical modeling of the problem. Obtained set of equations is resolved numerically through built-in command NDSolve in Mathematica. Influence of emerging parameters on thermal transport, pressure gradient, velocity and temperature profiles are presented graphically, and discussed physically. Temperature and velocity profiles of hybrid nanofluids show decreasing behavior with an augmentation in nanoparticles volume fraction, while reverse behavior is found for the heat transfer rate.
