Descrição: In this paper, the mechanism of radiative Oldroyd-B nanofluid flow over a rotating disk with activation energy and motile microorganisms is examined. The perspective of fluid flow due to disk rotation encompasses both theoretical and practical relevance of it in engineering and applied sciences. Nonlinear ordinary differential equations are firstly converted from the corresponding partial differential equations and are formerly renovated using appropriate transformation to achieve set of nondimensional equations that were subsequently solved by shooting technique. The solution for regulating flow equations is carried out with the execution of the prominent numerical method bvp4c built-in function of MATLAB software. The observed response is supported by a comparison with existing resources, and a comprehensive graphical representation has been taken into account for parameters such as Deborah number, buoyancy ratio parameter, thermophoresis, Brownian motion, Biot number, and for motile microorganisms. Graphs and tables demonstrate the pertinent flow characteristics of the governing problem.
