Abstract
The main interest of the current research study is, on the one hand,
to increase heat transfer of the base and mixture fluids by using
hybrid nanoparticles. By considering two types of boundary conditions such as insulated and convective tips, to explore numerically
and analytically the simultaneous impacts of the thermal radiative
and free convective flow of hybrid nanofluid via a moving porous
longitudinal fin. This investigation employs Darcy’s model and the
mixture base fluid H2O (50%)–C2H6O2 (50%). The governing equations have been solved by utilizing Runge–Kutta–Fehlberg 4th–5th
order technique (RKFT45) with shooting-scheme and analytically via
Duan–Rach Approach (DRA). It is found that the nondimensional
temperature θ (η) is a decreasing function of a wet porous number
m2 and convective parameter Nc for both insulated and convective
tips, and as an increasing function of ambient temperature θa, Peclet
number Pe and power index n. It is also found that the thermal profile θ (η) presents a decrease for all considered shape factors in the
cases of insulated and convective tips boundary conditions. Computational results and those obtainable in the previous works have been
used to verify and strengthen the results gained by the analytical DRA
technique.
