Magnetohydrodynamics Boundary Layer Flow of Hybrid Nanofluid in a Thin-Film Over an Unsteady Stretching Permeable Sheet

Abstract

This analysis explored the computational process of heat transfer analysis in a thin-film MHD flow embedded in the hybrid nanoparticles, which combine the spherical copper and alumina dispersed in ethylene glycol as the conventional heat transfer Newtonian fluid model over a stretching sheet. The nonlinear ordinary differential equations (ODEs) was attained by transforming partial differential equation (PDEs) as governing equations when implementing the similarity transformations technique. The resulting nonlinear ODEs have been utilized by using the Keller box method. The natures of the thin-film flow and heat transfer through the various values of the pertinent parameters: unsteadiness, nanoparticle volume fraction, thin-film thickness, magnetic interaction and intensity suction/injection are deliberated. The approximate results for velocity and temperature distributions and physical quantities in terms of local skin friction and Nusselt number have been obtained and analyzed via graphs and tables. As a consequence, the suction expresses a more prodigious effect on the hybrid nanofluid rather than injection fluid for all the investigation parameters. It is worth acknowledging that the existence of the nanoparticles and MHD in the viscous hybrid nanofluid tends to enhance the temperature profile but decay the particle movement in the thin-film flow. It is perceived that the velocity and temperature profiles decline for the growth of the unsteadiness, thin-film thickness and suction/injection parameters.

Magnetic Impact on the Unsteady Separated Stagnation-Point Flow of Hybrid Nanofluid with Viscous Dissipation and Joule Heating

“…The deterioration in Al 2 O 3 -Cu/H 2 O temperature improves the thermal transmission and gradually upsurges the heat transfer performance. Based on Figures 10 and 11, it is noted that all profiles asymptotically satisfy the free stream conditions (8), which then authorises the validity of the numerical solutions.…”

“…The conclusions are drawn for the flow field and other physical quantities of interest. The bvp4c solver in MATLAB software was used to solve Equations ( 6) and ( 7) with respect to boundary conditions (8), numerically. The reliability of the current results is confirmed by comparing the numerical data with Lok and Pop [45], Ishak et al [46], and Wang [47], as reported in Table 3.…”

We also mention some recently published papers by Kamis et al [8], Nadeem et al [9], Elsaid et al [10], Hassan et al [11], and Sheikholeslami [12], who presented a numerical simulation of boundary layer flow in a hybrid nanofluid considering various physical phenomena.…”

“…Researchers are interested in working on this topic because of its extensive applications in sectors such as coating material, industrial processes, chemical engineering, cooling and the lubrication of thermal changer fins into contact lens motion, dam breaking wave simulation and nuclear reactor fluid dynamics that are among the most significant industrial applications [25]. The TFF flow past a stretching sheet is numerically tackled by Kamis et al [26]. The representation of TFF dynamics is similar to tear films in the eye and membranes in the biophysics field [27].…”
