MHD flow of a micropolar hybrid nanofluid between two parallel disks

The focus of this chapter is to analyze the MHD flow of a micropolar hybrid nanofluid between two porous disks. The flow nature is significantly influenced by the microrotation of the hybrid nanoparticles. To provide clarity, a comparison between the analytical and numerical results is stated. In this study, TiO₂-Cu is chosen as the hybrid nanoparticle mixed with a water-based fluid. To simplify the governing partial differential equations (PDEs), a suitable transformation method is employed to convert them into ordinary differential equations (ODEs). The resulting nonlinear ODEs are then calculated by using the DTM. The influence of the Reynolds number, material, and magnetic parameters on the radial velocity and microrotation profile is visually depicted and explained through graphical illustrations. The calculated results obtained from DTM are compared and tabulated alongside the numerical method results. This comparison serves to demonstrate the accuracy and validity of DTM. Additionally, the coefficient of skin friction is tabulated and compared with the numerical results.
