Optimizing chemical reactive flow of diathermic oil-based trihybrid nanofluid with local thermal nonequilibrium effects for industrial heat transfer applications

Abstract

This paper investigates the effects of local thermal nonequilibrium and thermal radiation on the chemical reactive flow of a trihybrid nanofluid (THNF) around a rotating sphere in the presence of thermophoretic and electrophoretic particle deposition. The diamond, cobalt oxide (Co3O4), and titanium dioxide (TiO2) nanoparticles dispersed in diathermic oil comprise the THNF flow model. Such a model would be extremely helpful to industries that require efficient heat transfer in rotating systems, such as those found in nuclear reactors, turbine blades and rotary heat exchangers. The unique mix of Co3O4, TiO2 and diamond nanoparticles in diathermic oil enhances thermal conductivity and reactivity, boosting heat transfer stability and efficiency at high temperatures. Additionally, this model may promote applications in automotive and aerospace engineering, where thermal management is essential, by fostering developments in nanofluid-based cooling systems for electronics. The numerical solution of the simplified equations is obtained using a shooting technique and the bvp4c. Graphics are used to show the mathematical results. We look at how different limits affect their distinctive characteristics. The fluid and solid phases decrease when the porosity-modified conductivity ratio rises. The THNF rate of mass transfer values increase by 6.20% when the thermophoretic parameter value is increased from 0.1 to 0.6.
