Peristaltic transport of hybrid nanofluid under the effects of thermal radiation through asymmetric curved geometry: a numerical approach

Abstract

ABSTRACT Magnetohydrodynamics (MHD) has various applications in the field of medicine, particularly in drug delivery and hyperthermia treatment for cancer therapy to the affected area via peristaltic phenomena. Further elaboration is required to optimize the delivery method of hybrid nanoparticles with aluminum oxide and zinc oxide to the target area via the esophagus to get the best-desired results. Keeping the importance of MHD in mind, the present problem highlights the characteristics of Magnetohydrodynamics (MHD) peristaltic transport by incorporating the properties of nanoparticles of aluminum and zinc oxides when suspended in water through an asymmetric curved conduit. The governing equations are mathematically modeled under consideration of Hall current, viscous dissipation, ohmic heating, thermal radiation, and heat sink/source effects. The influence of magnetic field, velocity, and thermal slips is also considered. Negligible Reynolds number and long-wavelength approximations are used to overcome the complexity of the system. To compute the numerical solutions of the simplified nonlinear system, two different techniques are utilized via MATLAB and Mathematica. The outcomes of the different flow parameters on the hybrid nanofluid’s velocity, trapping phenomena, temperature distribution, heat transfer rates, and pressure gradient are analyzed through tables and graphs.
