Exploring the Impact of Interfacial Cluster MHD Nano-Lubricant Fluid Flow on Swirling Porous Disks: A Parametric Study

This research delves into the influence of interfacial cluster Magneto hydrodynamics (MHD) nano-lubricant fluid flow on swirling porous disks, employing a model featuring Zn–Al2O4 with water as the base fluid. Through the examination of various dimensionless parameters such as VDP, HTP, and MTP, the shear stress profile is found to be directly linked to the Magnetic parameter M, Volume fraction, and Sisko parameter Sp. Notably, an inverse relationship is observed between the expansion ratio and the permeable Reynolds number, alongside the shear stress profile. Additionally, an increase in volume fraction (θ1, θ2) results in a decrease in the Heat Transfer Profile (HTP). Moreover, the HTP, permeability Reynolds- Number, and Sisko parameter demonstrate a direct correlation, where the heat transfer initiates a decline with positive increments of the parameter, while showing an increase with negative increments. Furthermore, the injection/suction process occurring with the movements of swirling porous disks illustrates a reduction in the thickness of the thermal boundary layer on the HTP. This study provides valuable insights into the intricate dynamics of nano-lubricant fluid flow on swirling porous disks and contributes to the understanding of heat transfer and shear stress profiles in such systems.
