Graphene oxide nanoparticles oscillation in drilling fluid for heat transfer with entropy generation over radiative cylinder in fluctuating and laminar regimes

Abstract

The oscillatory motion of graphene oxide-Go nanoparticles in water lubricating Maxwell nanofluid flow for heat and mass transfer enhancement in steady and fluctuating regime is important significance of this study. The aim of this work indicates the temperature distribution, nanoparticle concentration rate and velocity field around stretching radiating-cylinder in drilling systems. The nonlinear radiating energy, entropy generation, mixed convection, buoyancy ratio and oscillatory effects are assumed for heat and mass performance. The partial differential based mathematical expressions are developed to estimate the values of current analysis. The oscillatory stokes conditions, complex variables, and primitive transformations are applied to develop steady and fluctuating results. The computational outputs are secured using very efficient methods like finite difference and Gaussian elimination. The graphical outputs are displayed through TecPlot-360 and FORTRAN. The fluid velocity field, energy, and concentration outputs are executed with the help of various physical factors. The steady friction and steady thermal rate are depicted and are used in transient algorithm to depict the fluctuating friction rate and oscillatory thermal-mass transport. The magnitude of fluid velocity, fluid temperature and fluid concentration enhances as Maxwell parameter is enhanced. The variation in fluid velocity amplitude and fluid temperature increases as radiating energy is enhanced. For high parametric range of Maxwell number, the steady skin friction and mass transfer increases but heat transfer decreases. At smaller Eckert number, the oscillations in transient skin friction, transient heat and mass transfer are enhanced. At higher Maxwell parameter, buoyancy and Schmidt number, the large amplitude in heat and mass oscillations is observed.
