Cattaneo-Christov heat flux model in radiative flow of (Fe3O4– TiO2/Transformer oil) and (Cu– TiO2/Transformer oil) magnetized hybrid nanofluids past through double rotating disks
Abstract
Recent progresses in nanotechnologies and nanoscience have led to the creation of hybrid nanofluids, which are a complicated category of fluids with superior thermal features to regular nanofluids. The current framework demonstrates the importance of a two-dimensional steady incompressible axisymmetric flow of Maxwell hybrid nanofluid over double disks with thermal radiation. This investigation analyzes a novel idea regarding the execution of the Cattaneo-Christov heat theory and melting phenomenon by considering transformer oil as a base fluid. Two dissimilar classes of hybrid nanofluid, Iron–Titanium oxide/Transformer oil (Fe3O4–TiO2/TO) and Copper–Titanium oxide/Transformer oil (Cu–TiO2/TO) have been taken into our research work. The main equations (PDEs)are translated into a present set of ODEs using the necessary similarity variables. In MATLAB, the shooting scheme is utilized to evaluate the numerical and graphical outcomes of physical flow parameters. The radial velocity rose as the volume fraction of nanoparticles increased. The radial velocity field is increased as the porosity parameter is enhanced. The temperature profile is decreased with increasing the values of the thermal redaction parameter. Furthermore, because of the higher compactness of the copper nanoparticles, the addition of the volume fraction of nanoparticles slows the flow profile, and because copper is an excellent conductor of heat, it raises the fluid temperature throughout the domain. The mathematical fallouts also tackle the idea of employing magnetized spinning discs in space engines and nuclear propulsion, and such a model carries useful applications in heat transfer enhancement in a wide range of industrial thermal management devices and renewable energy generation systems.
