Abstract
Time-dependent electrically conducting squeezing flow of micropolar nanofluid is analyzed between two parallel disks. The bottom porous disk is fixed while the upper disk moved orthogonally along axial direction. Nanofluid features such as thermophoresis and the Brownian motion are considered using the Buongiorno theory of nanoparticles. Cattaneo-Christov model (CCM) is executed in the expression of energy equation. Uniform suction/injection is considered at bottom disk. Inclined magnetic field is accounted at an acute angle along axial direction. The constitutive model is normalized by utilizing the similarity functions. The numerical solution of flow model is developed by MATLAB built-in bvp4c function. The physical parameters are explored through graphical depiction, two-dimensional contours, three-dimensional flow phenomenon and streamlines. Since, the micropolar parameters tend to move the fluid particles in opposite way. Therefore, micro-rotational field has an increasing tendency in the left half region and decreasing behavior in the right half plane of the central region. It is obtained that the temperature field is boost up against increased squeezing Reynolds number, parameter of thermal relaxation stress and Prandtl number. Brownian movement and thermophoretic factors have a reverse phenomenon on concentration curves.
