Abstract : Efficient heat transfer is very crucial for the various industries in electrical, nuclear power, aerospace and automobile fields. By exhibiting improved thermal conductivity, nanofluids have emerged as an alternative for enhanced thermal and energy efficiency applications. The present study examines the movement of nano fluid across a surface that extend when heat radiation and magnetic fields are present. Using appropriate similarity variables, governing partial differential equations are converted to nonlinear ordinary differential equations. Engineering factors which are discussed include Nusselt number and skin friction coefficient. Numerical analysis is optimized using the response surface methodology. The Response Surface Methodology (RSM) with face-centred Central Composite Design is utilized to calculate heat flux transfer at the stretched sheet. The interaction of heat radiation, magnetic field parameter, and solid volume fraction are investigated in the present work. It is worth noting that the local Nusselt number responds positively to the magnetic field parameter and the solid volume fraction, whereas the skin friction coefficient responds negatively.
