Enrichment of heat transfer mechanisms in a Cu-Al ₂ O ₃ /H ₂ O hybrid nanofluid flow over a Riga disk with emphasis of thermal radiation

The current work aims to investigate the analysis of the transmission of heat and mass in the hybrid nanofluid (HNF) flow due to the rotating and inclined Riga disk in the presence of heat radiation and chemical reactions. The novelty of the current work is to investigate the time-varying magnetic field on the unsteady slip flow across the riga disk. Both joule heating and viscous-dissipation components of the heat transmission process are taken into consideration. Copper and aluminum oxide suspended in the water make up the HNF. To convert the suggested system of nonlinear partial differential equations into a system of nonlinear ordinary differential equations with slip boundary conditions, an appropriate similarity transformation is applied. The differential transform method is then used to solve the amended equations. A more comprehensive understanding of this system’s heat and mass transfer properties can be obtained from graphs and showing the precise dimensions profile findings for different flow parameters. The porosity parameter, the unsteady factor, the Eckert, and Forchheimer number, all increase the temperature of HNF, whereas the radiation factor values cause the thermal heat to decrease close to the disk and increase away from it. According to the findings, adding thermal radiation significantly enhances and makes the heat transfer system more realistic. By comparing the produced results with established results and numerical method results, the accuracy of the result has been established and there is a good agreement between them. These results have significant relevance for heat transfer system design and optimization in engineering applications.
