Computational Mechanism of Melting Heat Transportation in Methanol-Based Nanofluid Flow between Rotating Disks

Abstract

Heat transmission enhancement in rotating disk systems is crucial for advanced engineering uses. However, the combined influence of Joule heating and melting heat transport on thermal properties of methanol-based nanofluid between rotating disks has remained unexplored. This article analyzes the flow and heat transfer characteristics of a magnetized nanofluid between disks. Here, methanol serves as a base fluid containing ferro and silicon carbide nanoparticles. The melting phenomenon is incorporated in this study. The Joule heating impacts due to magnetic field are discussed. Thermal and Joule heating irreversibility are considered in the current mathematical formulation. By applying suitable transformations, the modeled partial differential equations are reduced to dimensionless ordinary differential equations. The numerical algorithm named bvp4c is employed to solve the simplified, dimensionless governing system of ODEs, yielding a numerical solution. The influence of pertinent variables on radial and axial flow fields and temperature profiles are analyzed and displayed graphically. The nanofluid's radial velocity increases as the stretching rate of the bottom disk increases. The fluid's tangential velocity rises by boosting the rotation parameter. Raising the melting point and Eckert number enhances the heat transfer of Fe3O4-SiC/methanol nanofluid.
