Heat transfer in wall jet flow of magnetic-nanofluids with variable magnetic field

This study reports the enhanced heat transfer of electrically conducting magnetic-nanofluids with thermal radiation and inclined magnetic field effects. We consider water as a base fluid embedded with the two different types of aluminum alloy nanoparticles namely AA 7072 and AA 7075. AA 7072 is a special type of heat treatable aluminum alloy with 98% Al and 1% of Zn with the additives such as Si , Fe and Cu . Similarly, AA 7075 contains 90% Al , 5–6% Zn , 2–3% Mg , 1–2% Cu with the additives such as Si, Fe and Mn . Numerical results are explored with the aid of R-K and Newton’s techniques. Results are depicted diagrammatically and discussed on the common profiles of interest (velocity and temperature). The heat transfer rate of water-AA 7075 nanofluid is significantly high when compared with the rate of heat transfer of water-AA 7072 nanofluid.
