Abstract: This theoretical thermal continuation deals with the radiative flow of Williamson nanofluid subject to the inclusion of microorganisms. The further modification in the bio-convective model is done by incorporating the heat source/sink and activation energy phenomenon. The motivation for the choice of Williamson nanofluid is referred to multidisciplinary rheological impact which may enhance the heating phenomenon upon inclusion of nanoparticles. A bidirectional moving surface is the source of inducing flow patterns. The governing expressions which result via thermal model are numerically simulated with a shooting scheme. The impact of flow parameters is identified for velocity change, heat transfer rate, concentration, and microorganism profile. Moreover, the numerical results in terms of different tables are framed out for observing the fluctuated pattern of heat transfer, concentration impact, and microorganism change. The outcomes simulated from the model reflect that a lower velocity rate is results for the velocity ratio parameter. The external heat source attributed the enhancement of heat transfer. Moreover, the concentration profile improves with activation energy and convection constant.
