Numerical study for MHD peristaltic flow of nanofluid with variable viscosity in the porous channel

Abstract

AbstractRecent developments in biomedicine have raised the usage of silver (Ag) nanomaterials in enhancing the ability of drug delivery procedures. Magnetic fields are externally applied to guide the drugs towards a specific target. Peristalsis of nanofluid with variable viscosity is studied here. A porous media with varying porosity and permeability becomes saturated with the nanofluid. Temperature dependent viscosity and Maxwell's thermal conductivity models are adopted. Thermal and velocity slip constraints are considered in the study. Low Reynold number and long wavelength predictions are used to simplify governing equations. Simplified non‐dimensional equations are numerically tackled. NDSolve is built in shooting technique that are used in the Mathematica software. Effects of pertinent variables on pressure gradient, velocity, temperature and heat transport process are studied. Addition of silver nanoparticles enhances the heat transport characteristics. The axial velocity is reduced in the existence of an inclined magnetic aspects. Pressure gradient at the wall are increases by increasing the concentration of nanomaterial and magnetic field strength.
