| Abstract: | The variety of technical and industrial applications for nanofluid technologies has recently increased, as has their emphasis on specific industrial applications. This study focused on the flow of nanofluid between two stretchable spinning disks in the presence of a magnetic field and investigation of homogeneous and heterogeneous reactions with the Joule heating effect. Water-based nanofluid with titanium oxide (TiO2) and graphene oxide (GO) nanoparticles are taken into consideration. The governing boundary layer equations are transformed into nondimensional ordinary differential equations, and solved by using the bvp4c methodology. For the sake of engineering interest, the calculation of skin friction and Nusselt numbers for both cases are evaluated. In addition, the impact of different values of the involving factors on the axial, radial, and tangential velocities, temperature, and concentration profiles is discussed. It is observed that the Nusselt number for the lower disk increased for increasing values of magnetic parameter (M) and stretching parameter (A1), while decreasing for rotating parameter (Ω). The attained results of this study are compared with the latest published research studies. Also, noticed that the temperature is a decreasing function of Reynolds and Eckert numbers, and the concentration is a decreasing function of Schmidt number. [ABSTRACT FROM AUTHOR] |
