Improvement in thermal phenomenon due to bioconvective transport of third-grade nanomaterial with variable viscosity and convective boundary constraints: Sustainable energy developments

Novel attention has been devoted to renewable energy reservoirs in the current century. Thermal energy performance is significantly enhanced due to the interaction of nanoparticles. The motivated research indicates the applications of chemically reactive non-Newtonian nanofluid due to bioconvective phenomenon and radiated impact. The fundamentals of heat and mass transfer are analyzed considering the variable effects of viscosity and thermal conductivity. The convective thermal and mass constraints are utilized. A uniformly oscillated surface with a stretching phenomenon endorsed the flow. The governing problem is altered into a nonlinear partial differential system. The convergent approach is followed by simulations. The physical impact against variation of parameters is noticed. It is observed that variable considerations of viscosity and thermal conductivity contributes a beneficial impact for increment of thermal transport. The skin friction oscillates via a periodic approach, and the magnitude of oscillation is enhanced due to material parameters. The claimed results attain applications in the improvement of energy reservoirs and sustainable energy developments. The simulated observations reveal that heat transfer enhances due to third grade fluid parameter while declining effects are examined due to Reynolds number. The heat and mass transfer improves due to thermal Biot number and concentration Biot number, respectively. Moreover, the microorganisms profile enhanced with viscosity parameter.
