Energy and Mass Transfer Through Hybrid Nanofluids Flow Comprised of AA7072-AA7075 Nanoparticles Subject to Magnetic and Thermal Radiation on Stretching Surface

In the current analysis, the energy transport through a hybrid nanofluid (HNF) across a rotating as well as a stretching surface is evaluated. The HNF has been prepared by the dispersion of aluminum alloys (AA7072-AA7075) also known as aerospace aluminum or aircraft aluminum in water. Engineering systems use aluminum alloys with a broad range of characteristics. Due to the lighter weight of aluminum alloys, they are also used in vehicle engines, especially in crankcases and cylinder blocks. The flow of hybrid nanofluid is studied under the significance of thermal radiation, activation energy, heat source, and magnetic field. The flow phenomena are mathematically expressed in the form of a system of nonlinear PDEs. That system of PDEs is first transformed into the dimensionless system of ordinary differential equations (ODEs), by employing similarity variables and then solved through the MATLAB built-in package bvp4c. The results are derived for velocity, concentration, and energy curves versus diverse physical parameters. It has been observed that the temperature profile of hybrid nanoliquid rises with the mounting values of Eckert number, heat source, and thermal radiation. Furthermore, it can be noticed that the energy transference rate rises up to 9.9261% by the addition of AA7072-NPs in water, while in case of hybrid nanofluid, the energy transference rate rises up to12.8972%. It has been also noticed that the hybrid nanoliquid (AA7072-AA7075/water) has superior thermal characteristics than the simple nanofluid.
