Rotational impact on nanoscale particles Fe2O4, NiZnFe2O4, MnZnFe2O4 suspended in C2H6O2 confined between two stretchable disks: a computational study

This communication addresses the fluid and heat transfer flanked by two stretchable rotating disks influenced by the induced magnetic field. The fluid flows due to the rotation of the stretchable disks enclosing a nanofluid having nanoparticles of three distinct ferrite compounds. The mathematical formulation of the problem is performed in a cylindrical coordinate system. Similarity analysis is applied for the sake of simplification. The velocity, pressure, induced magnetic field, and temperature distributions accompanied by surface drag force and heat flux are computed numerically by employing implicit finite difference algorithm. Effects of important emerging parameters are addressed through graphs and tables. Some pivotal findings include that magnetic parameter and reciprocal magnetic Prandtl number contribute to increasing fluid pressure near the lower disk and the opposite trend is reported in the vicinity of the upper disk. The present investigation is a benchmark problem that has a promising future in geophysics, oil refinery, and the chemical processing industry.
