Description
Summary:A study is performed to explore the behavior of the MHD radiative MoS.sub.2-SiO.sub.2/kerosene oil (hybrid nanofluid) and MoS.sub.2/kerosene oil (nanofluid) flow between the two shrinking and rotating disks. The heat transfer mechanism is studied with the Cattaneo-Christov heat flux model, convective heating and the magnetic field. The novelty of the work is to examine the heat transport phenomena of the MoS.sub.2-SiO.sub.2/kerosene oil (hybrid nanofluid) and MoS.sub.2/kerosene oil (nanofluid) in a Darcy-Forchheimer porous medium along with the ohmic heating, thermal radiation, viscous dissipation and heat generation/absorption. The guiding mathematical equations are modified into the coupled and nonlinear ordinary differential equations using the similarity transformations, which are then numerically solved using the MATLAB's built-in function "bvp4c." Plots are provided to present the impact of physical parameters on the flow and temperature fields. The axial velocity, radial velocity and tangential velocity are found to be decreasing near the surface of lower disk with the increasing inertial coefficient, while the temperature increases with increasing values of the inertial coefficient. Importantly, the hybrid nanofluid has an augmented heat transport rate than the nanofluid at the lower disk, whereas contrary behavior is true at the upper disk. In addition, an increase in the inertial coefficient (F.sup.*) value from 3 to 7 causes an increment of 31.77% and 30.79% in the drag force at the lower plate for the hybrid nanofluid and nanofluid, respectively. Furthermore, an increase in the Eckert number (Ec) from 0.5 to 0.9 causes an increment of 79.29% and 79.32% in the heat transport rate at the upper plate for the hybrid nanofluid and nanofluid, respectively. Meteorology, meteorological, atmospheric research, biochemical engineering, power and transportation production, solar energy transformations, optoelectronic and sensing microfabrication, tumbler in polymer manufacture and other fields will benefit from this suggested model.
