Abstract

Background Bioconvection is a familiar phenomenon of fluid mechanics which explains the hydrodynamic unsteadiness and suspensions of upward swimming microorganisms. Hydrodynamic unsteadiness is due to coupling in physical properties such as fluid flows and density of microorganisms. Gyrotactic unsteadiness occurs when microorganisms are more dense than fluid. Microorganisms are very small creatures and cannot be perceived with the naked eye. Aim and Scope The main purpose of this research is to highlight the concept of the Nanofluid flow over the surface of Riga by the influence of microbes and to solve this scheme numerically by applying the convection conditions. One of the main aims is to study the useful effects of swirling microorganisms passing through the microfluidic on the surface of Riga, by adopting the Powell-Eyring model. Riga plates are used to complete turbulent impact and avoid boundary layer separation. Methodology The swirling microorganisms and Riga plates are used to mathematically process the flow of nanofluids under the influence of chemical reactions and convection conditions. Nanofluids are usually made of nanoparticles, such as metal carbide Sic, oxide ceramic Al_2 O_3, nitride-ALN and metal graphite. The shooting method is used to solve the obtained differential equations. Results For different values of Powell-Eyring parameter and modified Hartmann number, the wall shear stress shows both an increase and a decrease. It is observed that the spectrum of moving microorganisms shows the decreasing behavior gainst Peclet number and the biological convection Lewis number parameters.
