Unsteady magnetized Ree-Eyring radiative hybrid nanofluid flow over a permeable biaxial shrinking sheet with Cattaneo-Christov heat flux effect

Purpose: Utilizing hybrid nanofluids for everyday use is critical to improving heat transfer productivity, particularly for electronics cooling and industrial operations. This article numerically analyzes the flow of unsteady Ree-Eyring hybrid nanofluid through a biaxial stretched/shrinked sheet. Additionally taken into account is the influence of magnetohydrodynamic (MHD), and the energy is further enhanced by Cattaneo-Christov heat flux model and the effect of heat radiation. In this study we used water as the base fluid, copper and titanium nanoparticles are combined to create a hybrid nanofluid. Design/methodology/approach: Based on the previous assumption, the model is firstly expressed as partial differential equations (PDEs), which are then changed into ordinary differential equations (ODEs) by relevant similarity transformations. The resultant system of ODEs with constraints on boundaries is solved computationally with BVP4C (Shooting Method). Finding: Solutions are derived for both the temperature profile and velocity profiles, and also for Nusselt number and skin friction, with associated discussions and the presentation of relevant outcomes depicted using graphs and tables. The findings indicate that as the parameter for magnetism upsurged, the velocity distribution drops, however, the temperature distribution rises. The graphical results also show that for large values of stretching parameter the velocity profile upsurge, while temperature profile declined. The temperature profile increases for large value of thermal relaxation parameter. The data presented in the table indicate the coefficient of skin friction decrease in direction for large stretching parameters. Additionally, the Nusselt number declined for large thermal relaxation parameters. Originality/value: The paper investigates non-Newtonian Ree-Eyring hybrid nanofluid flow across biaxial stretched sheets while accounting for the Cattaneo-Christov heat flux model and the impacts of MHD. The authors point out a dearth of previous research on non-Newtonian hybrid nanofluid flow with similar parameters, and no analogous work has been published. A thorough mathematical analysis is conducted to demonstrate the model's consistency. The authors underline the uniqueness of their findings and confirm that they are original and not based on any other sources.
