Dynamic squeezing flow analysis of transient aluminium alloy nanomaterials under variable magnetism and exponential heat source between two parallel plates

High-strength aluminium alloy commonly used in widespread applications in manufacturing and industrial developments such as microelectromechanical systems (MEMS), nanoelectromechanical systems (NEMS) where thermal control is vital. An extensive analysis on the squeezing flow of a time-dependent alloy water based nanofluids comprised of AA7072 and AA7075 solid nanoparticles via two parallel plates is presented in this article. AA7072 alloy (Aluminium 96%–98%, Zinc 0.8%–1.3%, Magnesium 0.8%–1.2%, Copper 0.1%, Chromium 0.18%–0.28%, Silicon 0.15%, Iron 0.4%, and remaining maximum 0.15%) is usually have excellent corrosion resistance. However, AA7075 alloy (Aluminium 91.2%–94.2%, Zinc 6.1%, Magnesium 2.1%–2.9%, Copper 1.2%–2%, Chromium 0.18%–0.28%, Silicon < 0.4%, Iron < 0.5%, Manganese < 0.4%, Titanium < 0.2% and remaining < 0.15%) has excellent mechanical properties and but it requires protective coating for corrosion resistance. The interaction of a variable magnetic field, combined with the effects of Joule dissipation, an exponential heat source, and radiative heat, enhances the flow dynamics. The dimensionless form of the governing phenomena is obtained for the suitable implementation of the similarity rules and furthermore, the solution is obtained utilizing traditional shooting based Runge–Kutta fourth-order numerical scheme. The diversified role of the various factors on the flow profiles are deliberated briefly through graphs with a comparative analysis. However, the major findings of the study are; the variation of unsteadiness parameter shows a dual characteristic from the central region of the channel and the fluid temperature enhances for the increasing heat dissipation.
