| This study investigates the mass and heat transfer characterisations of a two-dimensional, steady-state, axisymmetric, incompressible, MHD, laminar hybrid (Au-Cu/Blood) nanofluid flow over a permeable porous stretched cylinder. The analysis considers various governing parameters, including the mixed convective parameter, concentration to thermal buoyancy ratio parameter, activation energy, chemical reaction parameter, curvature parameter, Hartmann number, Darcy number, heat source or sink parameter, radiation parameter and Eckert number. Tiwari-Das model is utilized to analyse the flow dynamics. Since blood exhibits Newtonian properties in arteries, large cavities and veins, this study assumes blood to be a Newtonian fluid with a Prandtl number of 21. A key innovation of this research is the application of the prescribed heat flux with thermal boundary constraint. Non-linear PDEs generate ODEs by employing similarity transformations. Numerical solutions are derived using BVP5C method in MATLAB, utilizing an approach of shooting technique. This study reveals that the velocity rises with progressive values of λ,N and γ, whereas an inverse trend is noticed with increasing Ha and Da. The temperature progresses, the hiking of γ,Ha,Da,Rd,Ec and Q, trend is opposite for λ. The profile of Concentration enhancing in E,γ hiking, while the trend is opposite for enhancing the λ,N,Rc and Sc. This work also exposes that as λ increases from 0.1 to 0.7, heat transmission rate and skin friction constant rise by 30% and 27% respectively, while the mass transfer rate declines by 8%. When E ranges from 1.0 to 2.5, heat and mass transmission rate, the skin friction constant exhibit slight increases of 0.1%, 1.4% and 0.1% respectively. As Rc varies from 1 to 7, reductions of 3%, 3.4% and 57% are observed in the skin friction constant, heat and mass transmission rate respectively. Accuracy of this model has been rigorously validated against existing data, demonstrating excellent reliability. | ||
