The presented study investigates the heat and mass transfer characteristics of hybrid nanofluid flow past an exponentially enlarging sheet, featuring both heat source and sink effects. A distinctive aspect of this work lies in its examination of slip conditions to understand the flow behavior of hybrid nanofluids. The nanofluid itself consists of a blend of copper (Cu) and metal oxide (Al2O3) nanoparticles suspended in blood, which serves as the base fluid. This choice of nanofluid composition is noteworthy due to its potential impact on enhancing heat and mass transfer processes. Similarity conversion technique is applied that effectively transforms the partial differential equations (PDEs) governing the system into a set of ordinary differential equations (ODEs). The utilization of tables and graphs aids in conveying the influence of various embedded parameters on the obtained results. This graphical representation of parameter effects is a distinctive feature of the study, facilitating a clearer understanding of the relationships between different variables. In the concluding remarks, the study's outcomes highlight several distinctive findings. Firstly, an increase in the heat-generating parameter leads to elevated temperature distribution along the expanding sheet. Secondly, the introduction of a magnetic parameter is found to dampen the velocity of the nanofluids, which presents an interesting avenue for exploration in terms of flow control. Thirdly, the concentration profile of the nanofluids experiences a decline as the Schmidt number, a dimensionless quantity representing the ratio of momentum diffusivity to mass diffusivity, increases. It concluded that the heat and mass transfer rate is greatly enhanced by the addition of copper and aluminium oxide. This observation is a unique contribution to the understanding of heat and mass transfer behavior in such systems. The significance of this research extends to various applications, particularly in the realms of chemical engineering, environmental remediation processes, and solar thermal systems.
