Numerical investigation of Ag‐CuO/water hybrid nanofluid flow past a moving oscillating cylinder with heat transfer

The prime intention of this manuscript is to explore numerically the heat transfer and flow features of two distinct fluids, to be precise hybrid nanofluid (Ag‐CuO/water) and nanofluid (CuO/water) over a moving oscillating cylinder. The leading equations which control the flow are worked out via a robust Crank–Nicolson technique. The impacts of crucial physical parameters on the velocity and temperature profiles accompanied by skin friction coefficient and Nusselt number have been graphically investigated. The current study explored that by selecting Ag‐CuO/water (hybrid nanofluid) as an operational fluid, superior heat transfer rate and reduced skin friction coefficient can be attained than CuO/water (nanofluid). Skin friction coefficient and the rate of heat transfer through Ag‐CuO/water can be enhanced by increasing Grashof number (Gr). However, skin friction coefficient weakens and Nusselt number augments by increasing nanoparticle volume fraction δ 2 . Rate of heat transfer can be reduced and skin friction coefficient can be increased by rising phase angle ωt .
