摘要
Hybrid nanofluid is a mixture of two different nanoparticles that offer better heat transfer performance and thermophysical properties than traditional heat transfer fluids (water, oil, and refrigerant-134A) and nanofluid with single nanoparticles. Here, a type of hybrid nanofluid containing single-wall carbon nanotubes (SWCNTs) and multi-wall carbon nanotubes (MWCNTs) nano-sized particles with water and refrigerant-134A as base fluid is analytically modeled to establish the problem of the steady laminar MHD stagnation-point flow of a SWCNT-MWCNT/water-refrigerant-134A hybrid nanofluid through a rotating disk. Further, the influence of partial slip, viscous dissipation, and thermal slip are examined. Variables of von Karman are being used to transform partial differential equations in ordinary differential equations, which are solved numerically applying boundary value problem solver (bvp4c) in the MATLAB software. A comparison table for specific cases is provided to see the accuracy of our numerical results with recent data. The velocity and temperature behavior are plotted for various parameters. It is perceived that the fluid temperature is higher for hybrid nanofluid as compared to simple nanofluid and reverse behavior is observed for radial velocity. Further, the azimuthal velocity diminishes with the increasing value of magnetic and velocity slip parameters.
