Hall and Ion Slip Effects on Hybrid Nanofluid Flow Between Two Rotating Disks Considering Distinct Shapes of Nanoparticles

The present work examines the Hall and ion slip effects on H2O-EG-based hybrid nanofluid flow between two spinning disks with convective heating and suction effects at the lower disk. Further, the novelty of the proposed model is strengthened by considering a thermal heat source/sink. The hybrid nanofluid contains Ag and TiO2 as suspended nanoparticles of varying shapes, viz. spherical, cylindrical and brick. The significance of non-linear thermal radiation, viscous and Joule dissipations is also considered. Moreover, stretching effects and velocity slip are imposed at both disks. The governing equations are simplified using suitable transformations and the numerical solutions are obtained using the shooting method employed through bvp4c in MATLAB. The effects of some pertinent flow parameters on velocity and temperature profiles are demonstrated through figures. An increased rate of nanofluid temperature is observed for cylindrical and brick-shaped nanoparticles as compared to spherical nanoparticles.
