Radiative MHD flow with viscoelastic slip in channel through semi-analytical approach

Abstract

The study examines heat transfer in viscoelastic fluid flow through an axisymmetric porous channel under the effects of velocity slip, thermal radiation, and a magnetic field. The governing equations are transformed into self-similar form and these equations are solved using Optimal Homotopy Analysis Method. The influence of slip, porosity, viscoelasticity, thermal conductivity, radiation, and magnetic parameters on velocity and temperature profiles is analyzed. Results shows that increasing slip condition near the wall reduces the temperature. High Reynolds number increases fluid velocity and reduces thermal boundary layer thickness, whereas small Reynolds number and high slip produces the thicker thermal layers.
