Thermophoretic particle deposition in thermo-bioconvection flow of diamond-SiC-Co₃O₄/water-based trihybrid nanofluid with oxytactic and gyrotactic microorganisms: biotechnological applications

Abstract
The present study investigates the impacts of heat generation and Marangoni convection on the thermophoretic particle deposition \r\nin chemical reactive flow of Diamond- SiC- Co3O4Water-based trihybrid nanofluid across a sheet with oxytactic and gyrotactic \r\nmicroorganisms. Gradients of surface tension are varied to find Marangoni convection. It can be used in a variety of industries, \r\nincluding welding, crystal formation, soap film stabilization, and drying silicon wafer. The trihybrid nanofluid \r\nDiamond- SiC- Co3O4H2O flow model is made up of nanoparticles of diamond (ND) , and cobalt oxide Co3O4 , silicon \r\ncarbide (SiC) dissolved in water H2O . This model has applications in advanced bioengineering and environmental processes, \r\nincluding biofuel generation, wastewater treatment, and medication delivery system improvement. Microorganisms improve mass \r\nand heat transfer, which is advantageous for biomedical applications and microfluidic systems. Furthermore, industrial processes \r\nneeding effective heat transfer, such cooling systems in biotechnology labs and reactors, can be optimized by the trihybrid nanofluid’s \r\nenhanced thermal characteristics. The constitutive equations were converted into ODEs using similarity variables, and then they \r\nwere resolved applying MATLAB’s bvp4c function. The outcomes demonstrate that the modified model more exactly indicates \r\nhigher heat transfer rates than the classical model. Concentration and oxytactic microorganism distributions decrease with increasing \r\nthermophoretic parameter
