Explore the impacts of thermal radiation on Oxytactic and Gyrotactic microbes in SWCNTs+MWCNTs /water based hybrid nanofluid with Soret-Dufour effects

Abstract

The current paper investigates the effect of thermal radiation on Darcy-Forchheimer flow of MHD hybrid nanofluid with Soret-Dufour effects and activation energy towards three distinct geometries (wedge, flat plate and cone) including motile Oxytactic and gyrotactic microbes. The proposed model has significant uses in a number of environmental and engineering process. It is essential for improving heat transfer efficiency in cooling systems based on nanofluids, including those used in nuclear reactors, electronic devices, and biomedical applications. Because oxytactic and gyrotactic bacteria are included, it is pertinent to wastewater treatment, as microbial activity promotes the breakdown of pollutants. By improving thermal management in hot conditions, the work also helps aerodynamic and aerospace engineering. By enhancing energy absorption and heat dissipation, thermal radiation's effects on SWCNTs (Single-wall carbon nanotubes) and MWCNTs (Multi-wall carbon nanotubes) nanoliquid further support renewable energy technologies like solar thermal systems. The SWCNTs and MWCNTs are added to water, which acts as the improper liquid, to generate a trihybrid fluid. The MATLAB Bvp4c method is used to solve the equations. The outcomes show that the flow towards the cone has the most significant density gradient of Oxytactic and gyrotactic microbes, as well as the highest rates of mass and heat transmission. The results of the present study will be useful for several microorganisms enhance transportation operations, architectural design systems, oil recovery systems, and medical sectors that use nanofluid.
