要約

Magnetohydrodynamic (MHD) flow of graphene oxide nanofluid between two concentric cylinders is investigated in this article. A uniform magnetic field is applied and Buongiorno model is used to develop the flow of graphene nanofluids including the influence of viscous dissipation effects and the effects of nanoparticle characteristics such as thermophoresis and Brownian motion. The modelled equations are transformed and are numerically solved using linearization method together with Chebyshev's spectral collocation method under slip and isothermal conditions. The impacts of embedded parameters on temperature, concentration and velocity profiles of the chosen nanofluid and their consequent impacts on the predominant cause for the generated entropy are studied. Finally, the obtained results are depicted and interpreted in detail. Furthermore, entropy generation is analysed and its irreversibilty is calculated. Also, the values of Nusselt number, Sherwood number and skin friction are tabulated.
