Magnetohydrodynamic Effects Due to Graphene Oxide Nanofluid Flow in Concentric Cylinders

Aggregated studies on graphene nanoparticles and magnetohydrodynamic (MHD) flow of nanofluids are important for the effective utilization of their striking thermophysical properties in extensive industrial and medical applications. This investigation is one such study to explore the MHD flow of water dispersed with graphene oxide nanoparticles in concentric cylinders. The model is developed by adapting Buongiorno nanofluid model including viscous dissipation effects and the impacts of nanoparticle attributes namely thermophoretic and Brownian diffusion. Spectral quasilinearization method with Chebyshev’s polynomials is adapted to solve the differential equations under convective conditions. On studying the effects of implanted parameters, it is found that the diffusive mass transfer enhancement by Hartmann and Eckert numbers is remarked, while Eckert number improves convective heat transfer and Hartmann number improves conductive heat transfer. Also, special cases of the results are quantitatively analysed and are found to agree with the literature. Furthermore, entropy generation analysis is presented.
