Peristalsis for MHD hybrid nanomaterial through asymmetric channel

Abstract

Objective here is to address impacts of MHD hybrid nanofluids (Fe2O3+Cu/H2O) on peristaltic transport in asymmetric channel. Porous space is taken. Analysis is constructed in the presence of radiation, dissipation, convection and Hall current. Further velocity and thermal slip boundary constraints are considered. Lubrication approach is employed to simplify the dimensionless forms of equations. Quantities of interest are described numerically. The shooting method is used to solve the governing differential systems employing Mathematica. Outcomes of Hartman number, Hall effect, permeability parameter, Grashof number and radiation parameter are analyzed graphically. Result indicates that temperature decreases by increasing the strength of nanomaterials. Axial velocity decays in the presence of Hartman number. Analysis of heat transport process is evaluated using tabulated values. Results show that heat process improved for Hartman number while the opposite behavior observed for Hall current.
