Nanofluid flow with multimedia physical features for conjugate mixed convection and radiation

•Energy conversion for an extrusion stretching sheet processing has been investigated.•Energy conversion conjugate conduction, convection and radiation problem has been solved.•Flow and heat transfer of nanofluids have been examined.•The excellent results have been achieved with earlier published results. In this study, energy conversion problems of conjugate conduction, convection and radiation heat and mass transfer with viscous dissipation and magnetic effects have been investigated. Governing equations including continuity equation, momentum equation, energy equation and heat conduction equation for nanofluid flow have been analyzed by a combination of similarity transformation and finite-difference method. For heat convection energy conversion aspect, some importance parameters applied to the system, such as buoyancy parameters Gt and Gc, radiative energy parameter k0, boundary proportional parameter Ab and Prandtl number Pr which can be produced positive effects for larger values of those parameters. For mass transfer energy conversion aspect, it has been obtained a larger effect with a larger value of Sc. For heat conduction aspect, it depends on the conduction–convection parameter Ncc, a larger Ncc number can be produced a larger heat conduction effect. The study work considers multimedia effects, so that it is also one kind of multimedia physical features study.
