The magnetohydrodynamic flow of a nanofluid over a curved exponentially stretching surface

Abstract

The magnetohydrodynamics flow of a nanofluid over an exponentially curved stretching surface is deeply focused in the current study. By using the assumption on the curved stretching surface, the governing equations are established. We obtain nonlinear partial differential equations by utilizing the boundary layer estimation on the Navier–Stokes condition. These equations are converted into nondimensional system ordinary differential equations, using a suitable similarity transformation. The governing system of equations is tackled through an analytical method. The impacts of different pertinent parameters involved in the governing equations are illustrated graphically, whereas the numerical values of R e s 1 2 C f , .25em R e s 1 2 S h s .25em , and R e s 1 2 N u are also tabulated. The velocity profile declines with an increase in values of magnetic parameter and porosity parameter. The temperature profile is increasing, when the value of a thermophoretic parameter and Brownian motion parameter increases. A higher activation energy displays a stronger concentration profile. The concentration profile decreases for increasing values of the Schmidt number. The concentration profile shows the inverse impact for increasing values of the thermophoretic parameter and Brownian motion parameter. The focus of this study was to examine the heat transfer rate of nanoparticles.

Thermally Dissipative Flow and Entropy Analysis for Electromagnetic Trihybrid Nanofluid Flow Past a Stretching Surface

“…These fluids have low thermal conductance that restrains their performance in different applications at the industrial level. The thermal conductance of these fluids can be enhanced by spreading solid particles as also proposed by Jawad et al These particles are, for example, carbon, silver, magnesium oxide, copper oxide, alumina, titanium oxide, and graphene, etc. Such a combination of the base fluid and solid nanoparticles is termed as nanofluid.…”

“…The curved surface for the fluid flow has many applications in the mechanical and automotive industry. Sanni et al [35], Jawad et al [36], and Saeed et al [37] have studied the fluid flow on a curved surface using various kinds of nanofluids for the heat transfer enhancement. Hayat et al [9,38], Rosca, and Pop [39] have explained the homogeneous-heterogeneous reaction phenomena using the curved surface for the flow pattern.…”

“…Brownian motion and thermophoresis effects on magnetohydrodynamics (MHD) mixed convective thin-film second-grade nanofluid flow with Hall effect and heat transfer past a stretching sheet has been pointed out by Khan et al 5 Gul et al 6,7 explored the film flow in MHD third grade fluid on a vertical belt and analysis of thin-film flow over a vertical oscillating belt. Jawad et al 8,9 conducted a detailed debate on time-dependent bioconvection Darcy-Forchheimer nanofluid flow through a horizontal channel and MHD flow of a nanofluid over a curved surface.
