Abstract

Present investigation based on the axisymmetric squeezing flow of various alloy nanofluids between parallel disks embedding with porous medium. To enhance the heat transfer properties we have considered two special type of alloy nanoparticles such as AA7072 which contains 98% of Aluminum (Al), 1% of Zink (Zn), rest Silica (Si), Iron (Fe), Copper (Cu), and AA7075 contains 90% of Al, 5%–6% of Zn, 3% of manganese (Mg), 1%–2% of Cu with additive Si, Fe, and Mn. The effects of velocity slip and temperature jump boundary conditions are also considered. Suitable similarity transformation along with Maxwell model physical properties for nanofluid are use to formulate the dimensionless governing ordinary differential equations. Physical significance of characterizing parameters are presented graphically and discussed. The numerical computations for engineering coefficients are shown in tabular form. In a comparative study, the current result shows a good correlation with the earlier established result that confirms the convergence of the solution methodology. Further, the major outcomes are laid down as: The velocity is more prominent for AA7075-water nanofluid in the first region for applied magnetic field whereas reverse impact is observed in the second region. The fluid temperature retards when there is a rise in thermal slip parameter. The shear rate of AA7072-water based nanofluid is higher than other nanofluid AA7075.
