In the recent era of science and technology scientists have influenced by the hybridization of nanofluids due to their advanced thermophysical features. Hybrid nanofluids have superior response to thermal conductivity than any other conventional nanofluids. Therefore, the present study investigates the Bödewadt flow of hybrid nanoliquid above a stretchable static disk located in the plane z=0. Bödewadt flow describes a stable and uniform angular rotation of liquid at a higher distance from the static disk. Such flow is characterized through pressure gradient in radial direction and is balanced with centrifugal forces. An incompressible homogeneous electrically conducting flow occupies its space at z≥0. Hybrid nanofluid is a mixture of nanoparticles Cu (copper) and TiO2 (titanium dioxide) with water considered as a base-fluid. Titanium dioxide reveals excellent photo catalytic attributes and hence is implemented in antibacterial/antiseptic compositions. Moreover, copper nano-ingredients metallic particles suggest suitable dye diminution and catalytic potential properties. Hall effect is encountered in the momentum equations to measure the magnetic field while radiation term is considered to address the energy analysis. The convective flow phenomenon is normalized by executing similarity functions. The reduced governing system is then solved in numerical manner using Runge-Kutta-Fehlberg (RKF-45) procedure. The flow phenomenon on velocity and thermal fields is discussed in graphical way. Three-dimensional flow visualization with two-dimensional contours and streamlines are portrayed as well. Moreover, the numeric data of local-Nusselt number shear stresses is computed against selected values of the physical parameters. The modification in Hall current magnifies the radial velocity field and reduces the velocity field along axial direction. The temperature field is enhanced by the increased variations in heat transfer Biot number. The influence of volume fractions results in modification of thermal profiles. |
