Thermal and solutal performance of Buongiorno’s nanofluid model by embedding into the Bingham fluid flow configured by heat generation and activation energy

This paper explores the three-dimensional steady non-Newtonian nanofluid flow due to a rotating disk by using Bingham fluid model. Moreover, we have extended our analysis by taking the consequence of thermal and solutal aspects due to heat generation and activation energy. The Buongiorno’s nanofluid model is considered to investigate the improvement occurs in the thermal conductivity due to thermophoresis and Brownian motion of nanoparticles in the base fluid. Applying Buongiorno’s nanofluid model to investigate the flow significance of Bingham fluid while taking activation energy and heat generation having several industries application, including the enhancing thermal performance in cooling technologies, industrial processes, biomedical devices, and energy systems are a few examples. Research on these coupled effects has the potential to make significant progress in domains that depend on the interaction of heat transport, fluid dynamics, and chemical reactions. This problem is modeled by utilizing equation of continuity, Cauchy momentum equation, law of conservation of heat and energy. Within the range of a high Reynolds number, the boundary-layer flow is measured by using a similarity solution. The flow forming partial differential equations are altered into ordinary ones via suitable transformations. The solutions (numerical and graphical) are attained by solving emerging ordinary differential equations using bvp4c method on MATLAB software. The results have been argued and displayed through graphs in order to examine how the velocity, temperature and concentration distribution are affected by dimensionless parameters. The radial velocity decreases with raising magnitude of Bingham number whereas the increment happens in the tangential velocity due to Bingham number. The axial velocity profile turn-up with growing magnitude of Bingham number implying that the fluid quantity drawn from the surroundings is decreased. The temperature profile turn-up with growing magnitude of heat generation/absorption constraint, Damkohler number, Brownian motion number and thermophoresis constraint, while the concentration gradient turn-down with high magnitude of Damkohler number, temperature difference parameter and Brownian motion number. The novelty relays on the investigation of thermal and solutal enhancement happen due to the additions of nanoparticles in the Bingham fluid which is flowing on the rotating disk.
