Abstract
This study elaborates the incompressible and steady flow phenomenon of non-Newtonian (micropolar-Casson) fluids confined in two parallel porous disks. The fluid motion is generated due to the uniform injection along the axial direction at the stationary disks. The thermal execution of the system is augmented by the Buongiorno and Cattaneo-Christov theories. The velocity and thermal slip effects are also encountered through boundary conditions. To perform the numerical solutions, the flow governing system is first converted into a system of ordinary differential equations and then these reduced equations are solved by implementing the Runge-Kutta-Fehlberg's fourth-fifth (RKF-45) order method accompanied with a shooting scheme. The major outcomes of the study reveal that for increasing levels of magnetic factor and vortex viscosity, radial velocity decreases in the center plane and increases closer to the upper and lower disks. For varied magnetic parameter and vortex viscosity factors, the microrotation profile upswings at the bottom and upper disks, while the central plane shows an opposing tendency. The concentration profiles exhibit rising behavior for enhanced values of Schmidt number, whereas a reverse trend can be seen for the thermophoretic parameter.
