Modeling and design considerations for heat and mass transfer with diamond-cobalt oxide/ethylene glycol boger hybrid nanofluid in industrial systems

Abstract

The proposed study scrutinizes the effect of Stefan blowing on an axisymmetric flow of radiative Boger Diamond − C o 3 O 4 / C 2 H 6 O 2 -based hybrid nanofluid across an infinite disk with a Marangoni convection. The Cattaneo-Christov flux model is used to study the properties of thermal transmission. Because it incorporates thermal relaxation time, this new heat flux model is more complete than the original Fourier's law. To claim the characteristics of the hybrid nanofluid model, diamond and C o 3 O 4 nanoparticles are combined with C 2 H 6 O 2 -based base fluid. This model is especially important for increasing the efficacy of chemical reactors, refining material processing techniques, and streamlining microelectronic heating and cooling systems. Additionally, it can be used in the creation of complex lubrication systems and in medicinal contexts where precise control over temperature and mass transmission is required, such as in thermal therapy or targeted drug delivery systems. The appropriate variables are applied to change the system of PDEs into a non-linear ODEs system. Numerical solutions to this problem are found utilizing the Bvp4c approach. Tables and graphs are used to analyze the impacts of different physical and flow parameters on thermal, concentration, and flow behavior as well as the rate of mass/heat phenomenon. The results show that temperature, mass transmission rate, and heat transmission decrease, fluid flow increases as the Stefan blowing parameter increases.
