MHD stagnation point flow of hybrid nanofluid over a permeable cylinder with homogeneous and heterogenous reaction

Abstract

This investigation is addressed to examine the comparative consequence of thermal radiation and heat generation/absorption in steady three-dimensional MHD (Magneto-hydrodynamics) stagnation point flow of (MWCNTs + Cu/engine oil) hybrid nanofluid over a porous circular cylinder. Flow via thermal slip effect is inspected. Also, the impact of both homogeneous/heterogeneous (h–h) chemical reactions are considered for explanation of mass transportation characteristics. Here, a kind of hybrid nanofluid including MWCNTs (multi wall carbon nanotubes) and Cu(Coper) nanoparticles with engine oil as base fluid is used. Appropriate transformation procedure is implemented for renovating model expression of continuity, momentum, energy, mass transportation and boundary conditions into a set of ODEs. HAM (Homotopy Analysis Method) methodology is then employed to solve these nonlinear coupled ODEs. Furthermore, the influence of inserting model factors on velocities, temperature fields, C f (skin friction coefficient) and Nu (Nusselt number) has been investigated numerically and graphically. The core outcome specifies that hybrid nanofluid (MWCNTs + Cu + engine oil) improve thermal conductivity when equated with nanofluid (MWCNTs + engine oil).

Numerical Computation of Hybrid Carbon Nanotubes Flow over a Stretching/Shrinking Vertical Cylinder in Presence of Thermal Radiation and Hydromagnetic

“…To investigate the solution's stability, a small perturbation also needs to be taken into consideration in which f (η) = f 0 (η) and θ(η) = θ 0 (η). Moreover, upon differentiating Equation (19) and equating it to Equations ( 16) and ( 17) with τ = 0 yields the linearized equations given below:…”

“…Furthermore, [18] examines the lower stagnation point flow over a horizontal circular cylinder of brinkman-viscoelastic fluid. [19] explore the use of homogeneous and heterogenous reaction over a permeable cylinder. The work on stagnation flow with the effect of slip continued to be investigated by [20].…”

Dual solutions for MHD hybrid nanofluid stagnation point flow due to a radially shrinking disk with convective boundary condition

“…Dual solutions were found in this study, and the stability analysis identifies the first solution as stable and meaningful. Other studies on stagnation point flow of hybrid nanofluid were carried out by Jakeer and Reddy (2020), Zainal et al (2020b), Nasir et al (2020), Alghamdi et al (2021), Khan et al (2021b), Arani and Aberoumand (2021), Waini et al (2022b), Jawad et al (2022), Kamal et al (2022) and Zainal et al (2022). Very good references on nanofluids and hybrid nanofluids can be found in the books by Das et al (2008), Nield and Bejan (2017), Shenoy et al (2016) and Merkin et al (2021).…”

Mixed convectional and chemical reactive flow of nanofluid with slanted MHD on moving permeable stretching/shrinking sheet through nonlinear radiation, energy omission

“…Rehman et al [20] examined the nanofluid motion and energy transmission of at a stagnation on a continuously extending medium affected by the magnetization. The mathematical formulation of nanoliquid stagnation motion associated with energy and mass transport on a rolling surface with slip velocity was explored by Khashi'ie et al [21] Nasir et al [22] explored the effects of radiation and heat source in a 3D magnetohydro-dynamics stagnation flow of engine oil based MWCNTs+Cuhybrid nanofluid through a permeable spherical tube. Recently some other investigations such as Waini et al, [23,24] may be reported in the literature to visualize the stagnation flow of fluid in different geometries under various conditions.…”
