Abstract
The current study examines a hydrothermal model that accounts for the impacts of both homogeneous and heterogeneous chemical reactions on hybrid nanofluid flow between squeezing plates, Joule heating and viscous dissipation with the effect of nanoparticle concentration. Ethylene glycol with water was combined to create the base fluid. Alumina and copper (Cu) nanoparticles were then dispersed into this base, forming the hybrid nanofluid. A mathematical and analytical model that depicts fluid flow has been created. The system of governing equations has been simplified by invoking the similarity transformation. The resulting governing equations system is solved successfully with the help of BVP4c and homotopy analysis methods (HAM). We obtained the best agreement between the numerical and analytical results. A rise in the volume percentage of nanoparticles corresponds to an increase in the rate for heat transfer. The relationship between the heat transfer rate of hybrid nanofluids (HNF) and single nanofluids (SNF) is also investigated. Graphs are plotted to examine the impacts of physical parameters on velocity, temperature and nanoparticle concentration distributions. Skin friction coefficient, Nusselt and Sherwood numbers are analyzed numerically.
期刊介绍:
The International Journal of Heat and Fluid Flow welcomes high-quality original contributions on experimental, computational, and physical aspects of convective heat transfer and fluid dynamics relevant to engineering or the environment, including multiphase and microscale flows.
Papers reporting the application of these disciplines to design and development, with emphasis on new technological fields, are also welcomed. Some of these new fields include microscale electronic and mechanical systems; medical and biological systems; and thermal and flow control in both the internal and external environment.
