Aims: In the current study, the flow of Carreau nano-fluid through the stretched cylinder is subject to the influences of activation energy and heat source/sink with the Cattaneo-Christov heat fluxes model studied. Applications in recent times are the purpose of better heat and mass transport nanoparticles used for this purpose because of their better thermal conductivity than normal fluids. Nanofluids are used in medicines like agricultural sprays and with time it is used in the microprocessor for cooling and also used in the refrigeration industry as coolant. Methodology: The mathematical model was developed by taking these things into account and getting a model of nonlinear partial differential equations for administering this problem. These governing equations system modified into a system of ODE by utilizing appropriate similarity transform. For numerical computation or simulation, the ‘bvp4c’ built-in package of MATLAB is used to implement the shooting technique. Smooth implementation took place by introducing a set of variables to make our system dimensionless. Results/Conclusion: Graphical representation depicts the profiles of concentration, velocity, thermal, and microorganism density, and the impacts of various modeling quantities on these profiles are also discussed and elaborated. In tabular analysis, a contrast of computed outcomes with the previously available outcomes shows the accuracy of our computed results at different values of physical parameters. The presence of motile microorganisms improved the heat transfer rate.

The current study aims to explore the magnetic field on a spinning disk with the hybrid nanofluid flow and Cattaneo-Christov heat theory in the existence of nonlinear thermal radiation incorporating Ag and MnZnFe2O4 nanoparticles. Because silver may increase the thermal characteristics of the base material, it has a wide variety of industrial, pharmaceutical, power generation, and heating and cooling applications. The thermal properties of a hybrid nanofluid were to be found by exploring the aspect of nanomaterials on heat transfer and fluid flow. The principal partial differential equations are converted into ordinary differential equations using appropriate similarity treatments. With the aid of the shooting strategy, higher-order ordinary differential equations are converted to first-order ordinary differential equations. To present the numerical data and graphical results of the flow parameters, the built-in solver Bvp4c in the computational tool MATLAB is used. Several plots are also used to investigate the upshot of physical parameters on the graphically depicted profiles, such as the suction and injection parameter, magnetic parameter, Prandtl number, temperature ratio parameter, thermal radiation parameter, thermal relaxation parameter, and volume friction nanoparticles. For the magnetic parameter, both velocity profiles dropped, but the heat profile increased. When the temperature ratio and heat source-sink parameters were increased while the Prandtl number was decreased, the heat field increased.
