The fluid flow under the slip effects present many dynamical applications in petroleum engineering, soil sciences,
aerodynamics, thermal systems etc. The aim of current investigation is to observe the heat transfer phenomenon
in magnetized flow of viscous fluid due channel with lower unbend wall. The fluid flow is altered due
to interaction of slip effects. The injection phenomenon for porous medium has been considered. For heat
transfer investigation, viscous dissipation applications are endorsed. The fundamental problem is modelled with
associated laws. The variational iteration method (VIM) scheme is proposed to simulate the analytical outcomes.
The numerical results for Nusselt number and skin friction coefficient are depicted and analysed graphically.
The summarized observations convey that control of heat transfer is improved with interaction of slip
phenomenon. The declining result for Nusselt number is referred to suction parameter.
