Numerical Simulation of 3D Darcy-Forchheimer Hybrid Nanofluid Flow with Heat Source/Sink and Partial Slip Effect across a Spinning Disc

The current study explains the numerical simulation for the Darcy-Forchheimer (DF) hybrid nanofluid (HNF) flow over 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 its light weight and durability. Additionally, making of M16 rifles for the American military is one intriguing application of the 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 ordinary system of differential equations (ODEs) by substituting similarity variables. The obtained set of equations is solved via using PCM (parametric continuation method). It has been noticed that the HNF both radial and axial velocity diminish with the upshot of porosity parameter and Darcy Forchheimer term. The velocity and temperature fields reduce with the rising numbers of aluminum alloys (AA7072 and AA7075).
