Numerical investigation of bioconvective non-Newtonian nanofluid flow across a curved surface in the presence of microbes

Abstract

The industrial implications of bioconvective non-Newtonian nanofluids can provide valuable insights. For example, studying their use in wastewater treatment, oil recovery, or cooling systems could have significant practical benefits. Nanomaterials possess influential thermal attributes and convincing utilizations such as in transfer of thermal energy, electric cooling system, biopharmaceutical, food industry and solar power generation. The purpose of this article is numerical solution of Bio-convective non-Newtonian nanofluid flow through a stretching surface subject to presence of microorganism. The significance uses of nanoparticles motivated to establish the mathematical model which examines mass and thermal transmission of motile organisms in the presence of the electromagnetic field, heat conductivity, nonlinear thermal radiation, chemical impact and viscous intemperance. The bioconvection effects are scrutinized in the presence of microbes. The governing non-linear partial differential equations of heat transfer and mass flux have been modified into ordinary differential equations by employing the similarity transformations. Numerical solution has been generated through MATLAB inbuilt package ‘bvp4c'. The significance of various non-dimensional parameters deliberately discussed including exponential heat source, transfer of heat, velocity slip, and temperature concentration profiles and demonstrated graphically. Further, the consequential effects of parametric values and local Nusselt number, motile organism's number, corresponding Biot and Schmidt values, heat radiation, and microorganism concentration are visualized graphically.
