Abstract
The current study explains the numerical simulation for the Darcy-Forchheimer (DF) hybrid nanofluid (HNF) flow across a permeable rotating disc. The HNF is prepared with the addition of AA7072 and AA7075 (aluminum alloys) nanoparticles (NPs) in water. Aluminum alloys are frequently used in aircraft parts like fuselages and wing flaps due to their lightweight and durability. Additionally, making M16 rifles for the American military is another intriguing application of aluminum alloys. The fluid flow has been estimated with the significances of thermal radiation, DF effect, viscous dissipation, thermal slip condition, and exponential heat source/sink. The modeled equations are simplified to an ordinary system of differential equations (ODEs) by substituting similarity variables. The obtained set of equations is solved using the parametric continuation method (PCM). It has been noticed that with the HNF, both the radial and axial velocity diminishes with the upshot of the porosity parameter and DF term. The velocity and temperature fields reduce with the rising numbers of aluminum alloys (AA7072 and AA7075).
