Enhanced thermal analysis of thermo-bioconvection flow of water based trihybrid nanofluid with gyrotactic microbes: soret and dufour effects

The suggested model of thermo-bioconvection flow of a water-based trihybrid nanofluid including gyrotactic microbes under Soret and Dufour effects has important applications in engineering and biomedicine. It can be used to improve mass and heat transmission in bioreactors, microfluidic devices, and wastewater treatment systems, where microbial activity is critical. Furthermore, it offers insights into enhancing thermal management in energy systems, cooling technologies, and sophisticated nanofluid-based biological processes including targeted medication delivery and microbial fuel cells. This study uses Soret and Dufour effects to describe how thermal radiation affects gyrotactic microorganisms in a water-based trihybrid nanofluid across a narrow porous surface. The impacts of magnetic fields and Hall current are all taken into consideration when analyzing fluid flow. The similarity transformation reduces a nonlinear set of PDEs to a dimensionless system of ODEs. We have used the bvp4c approach to numerically evaluate the reduced set of nonlinear ODEs. Thermal and concentration profile decline as augment the values of Marangoni convection parameter. As the values of the Marangoni convection parameter increase, the thermal and concentration profiles decrease.
