Magnetic dissipation on radiative free convection of a conducting hybrid nanofluid within a rotating cone and circular disc

Abstract

A significant attention is gained on the thermophysical properties corresponding to hybrid nanofluid flow within a rotating cone and circular disc in this present investigation due to its several applications. The enhanced thermal conductivity of the nanofluid is particularly useful in cooling systems, reducing energy consumption in systems, preventing overheating, and improving the overall performance of electronic gadgets, etc. In the present investigation, the free convective flow of conducting fluid for the interaction of magnetic field and thermal radiation encases their greater impact on the flow phenomena. Further, the assumption of dissipative heat i.e. mutual effects of viscous and Joule, energies the flow properties. The complex nonlinear form of the constitutive equations presented in the dimensional form is renovated into the nonlinear ordinary system with a non-dimensional form by introducing suitable similarity rules. The computation of the profiles is obtained numerically with the help of the built-in function bvp4c in MATLAB and depicted graphically. Finally, it is observed that the volume fraction of both the nanoparticles favors enhancing the heat transport phenomena due to the augmented thermal conductivity whereas a dual characteristic is revealed at both the surfaces of the circular disc and the cone.
